Greetings from Fluent & Fearless,

Some business phrases analyze. Others decide. In the last (probably) of our series on overly popular phrases, we look at “Let’s do it!” and “Let’s do this!” Short, energetic ways to say: “We agree, we are ready, and it is time to act!” The enthusiasm is part of the appeal. It is also why the expression has become so common in meetings, team chats, sales calls, and motivational workplace language that it can occasionally sound more automatic than decisive.

English Phrase: “Let’s do it! / Let’s do this!”

Meaning: Both expressions mean let us proceed, let us begin, or we are ready to take action. “Let’s do it!” often follows a specific proposal or decision. “Let’s do this!” can sound slightly more motivational, especially before starting something challenging.

Where the Phrase Comes From: “Let’s” is the contracted form of “let us.” The expressions developed naturally from everyday spoken English as simple ways to move from discussion to action. Over time, “Let’s do this!” especially became associated with enthusiasm, confidence, teamwork, sports, advertising, and motivational language. That energy transferred easily into the workplace.

Example Sentences:

Quick Tip: Discussion is finished. Action begins.

Common mistake: Using “Let’s do it!” before everyone understands what action has actually been agreed upon. The phrase depends heavily on context. Everyone needs to understand what it or this refers to, otherwise it sounds like premature enthusiasm.

Examples:

Enthusiasm does not replace a decision. If several possibilities are still open, identify the chosen action first.

“Let’s do this!” usually stands as its own motivational expression. It does not naturally replace a specific action verb like use, launch, or approve.

Memory Trick: If the action is not obvious, name the action. Because “Let’s do this!” is now so familiar in motivational language, using it selectively gives it more impact.

Spotlight: Replacing Nominalizations With Direct Verbs

What Is It? A nominalization happens when a verb is turned into a noun, often making business writing longer and heavier than necessary. Words ending in “-tion,” “-ment,” or “-ance” sometimes hide a simpler action. Replacing them with direct verbs can make instructions and decisions easier to read.

Examples:

Determine communicates the same action more directly than make a determination.

The revised sentence removes unnecessary wording and puts the action at the center.

Quick Tip: When you see make, conduct, or perform followed by an abstract noun, check whether one direct verb can replace both words.

Nota en español: En inglés profesional, convertir verbos en sustantivos puede hacer que una oración suene más pesada. Un verbo directo suele producir una frase más clara y natural.

“Let’s do this!” is effective because it compresses several ideas into three words: agreement, confidence, energy, and readiness to act. After a long discussion, those words can feel like a clean break between planning and execution.

That simplicity explains why the phrase has traveled so easily from casual conversation into sports, advertising, team meetings, project chats, sales environments, and leadership language. It sounds active and optimistic, which makes it tempting to use whenever a group needs a quick burst of momentum.

The problem appears when enthusiasm arrives before clarity. A team can enthusiastically agree to “do this” while different people have completely different ideas about what happens next. One person thinks the project begins Monday. Another thinks the proposal still needs approval. Someone else believes the budget has already been confirmed.

In that situation, “Let’s do this!” sounds decisive without actually creating a decision.

Strong business communication connects energy to action. Instead of ending a meeting with only “Great, let’s do this,” a leader might say, “We’re moving forward with Option B. Finance confirms the budget tomorrow, and the project starts Monday. Let’s do this.”

The enthusiasm remains, but now it has direction.

That distinction is especially useful in bilingual and cross-cultural teams. Informal motivational language may feel natural to some people and vague or unusually enthusiastic to others. Clear next steps make the phrase easier to interpret regardless of communication style.

There is also a matter of frequency. A phrase designed to signal commitment becomes less meaningful when it appears after every routine decision. Approving a major launch may deserve “Let’s do this!” Choosing a new spreadsheet template probably does not need the same level of drama.

The phrase works because it creates a moment. If every moment gets the same enthusiastic response, the signal becomes background noise.

Used selectively, “Let’s do this!” still does something valuable. It tells the group that consideration has ended and commitment has begun. The best version simply makes sure everyone is committing to the same thing.

Here’s what this principle looks like in practice.

Case Study: A consulting team spent two meetings debating three possible approaches for a client project. Near the end of the second meeting, the director said, “Option two gives us the clearest path. We’ll revise the timeline today and send it tomorrow. Let’s do it.” The phrase worked because the decision had already been defined. Nobody left wondering what had been approved or what happened next. Enthusiasm did not replace clarity. It reinforced it.

Lesson(s) Learned: Let’s do it! and “Let’s do this!” are useful expressions for moving from agreement to action. Their energy is strongest when the decision is clear, the next step is understood, and the phrase is not doing all the work by itself.

Strategic Question: When you say “Let’s do this,” could everyone in the conversation explain exactly what happens next?

Idiom: “Let’s get to work.”

Meaning: A direct way to say that discussion or preparation is finished and work should begin.

Example:

Cultural Note: “Let’s get to work” is less motivational than “Let’s do this!” and more directly connected to action. It can sound practical and grounded when extra enthusiasm is unnecessary.

Spanish Equivalent: “Pongámonos a trabajar”.

Significado: Expresión directa para indicar que es momento de comenzar el trabajo.

Ejemplo:

Nota: Pongámonos a trabajar es más literal y práctico. Manos a la obra añade un poco más de energía y sentido de impulso.

Riddle of the Week:
I do not settle for yesterday’s best,
I ask for something more.
I lift the standard higher
Than where it stood before.

Hint: This phrase means increasing expectations, standards, or performance.

Answer: Raise the bar.

“Let’s do it!” and “Let’s do this!” are popular colloquial expressions for turning agreement into action. They communicate enthusiasm, confidence, and readiness, which explains why they have become fixtures of modern workplace language. Their popularity can also make them sound automatic, so the strongest use is selective and specific: define the decision, clarify the next step, and then let the enthusiasm do its job.
