Fast to Decide, Slow to Act - MAC125

"Be quick to decide…but slow to act." This isn't just a pithy saying you nod along to and forget; there's real weight behind it. It's a quiet strategy that shows up again and again in fast career growth and strong professional reputations. If you've ever watched someone get promoted and thought, That seemed sudden, there's a good chance this was part of the story. From the outside, it looks like an overnight decision; behind the scenes, it's anything but. They were making clear decisions early, then deliberately working the back-channels; socializing ideas, pressure-testing assumptions, and building confidence in the outcome before taking visible action. This week, we're taking a deeper look at how this strategy actually works…and how you can apply it at any stage of your career. Most professionals make the mistake of reversing the adage. They sit with a decision; weighing possibilities, scanning for trouble spots, and searching for more data to increase confidence in the "right" answer. This approach feels responsible. Thoughtful, even. The intent is good; no one wants to make a bad call; especially one that's visible. So the decision gets pushed later and later; right up to the point where it can't be delayed any further. Then something subtle but costly happens. Once the decision is finally made, the switch flips. Action has to be immediate because there's no runway left. The plan is announced in an email or unveiled in a meeting; fully formed and already in motion. Almost instantly, resistance shows up. Concerns are raised. Questions surface. The data gets analyzed and reanalyzed. Stakeholders ask why they weren't involved sooner. From the perspective of the decision-maker, this feels like friction or second-guessing. From everyone else's perspective, it feels abrupt. And even when the decision itself is solid, it's now at risk; not because it's wrong, but because people haven't had time to absorb it. This resistance isn't politics in the way most people mean it. It's not sabotage, or ego, or a hidden agenda suddenly emerging at the worst possible time. It's a predictable organizational response to surprise. Humans don't resist decisions; they resist being surprised by decisions that affect them. When a fully formed plan appears without warning, people instinctively shift into evaluation mode. They ask questions not because they oppose the outcome, but because their brains are trying to close the gap between what just happened and how did we get here. The more consequential the decision, the stronger this reaction becomes. What feels like friction is often just the organization doing what it always does when it's caught flat-footed; slowing things down to regain a sense of understanding and control. Back to the adage. "Be quick to decide, but slow to act." The first thing to internalize is that deciding is not the same as announcing. Many professionals conflate the two; assuming a decision only exists once it's public. In reality, the decision is simply the moment you stop debating and start moving forward. It's the point where second-guessing ends. Where hesitation fades. Where you stop asking should we and start asking how do we position this. Deciding early creates internal clarity; and that clarity is what allows everything that follows to be intentional rather than reactive. Once that decision is made, action doesn't mean immediate implementation. There is a critical phase between the decision point and the execution point; and this phase is where careers quietly accelerate. Instead of rushing to roll something out, high performers use this time to socialize the decision with the people who have influence over whether it succeeds. They invite pressure. They ask for pushback. Not to abandon the idea, but to strengthen it. They win over influencers early. This signals competence. It signals leadership. It builds momentum before anything is formally announced. And when the decision finally reaches the wider group, it no longer feels abrupt; it feels inevitable. That's when things take off. Before going further, there's one detour worth taking. Jeff Bezos popularized the idea of one-way door and two-way door decisions. One-way door decisions are difficult or impossible to reverse. Two-way door decisions are easier to unwind. Both types should be decided quickly; but one-way door decisions demand a longer, more deliberate socialization phase. This is where assumptions get challenged, risks get surfaced, and the decision gets reinforced. When a decision can't easily be undone, that strengthening process isn't optional; it's what makes the eventual action durable. Let me offer a concrete formula you can use at any career level. It's deliberately simple; because complexity creates hesitation. Decide. Seed. Shape. Act. First; Decide. This is internal work. No audience. No deck. No Slack message. You decide what you believe should happen and why. Not perfectly...
