Two Things That Shape Your Life: Luck and Your Decisions

There’s something about this sentence that keeps returning to my thoughts.

Simple at first, but it grows on you.

There are only two things that determine how your life turns out: luck and the quality of your decisions. And you have control over only one of them.

That thought comes from Annie Duke in her book How to Decide.

And I keep coming back to it, because it challenges how we look at success, failure, and everything in between.

We like to believe we’re in control. That hard work always pays off. That smart people win. That doing the right thing guarantees a good outcome.

But that’s not really how the world works.

Luck plays a massive role. And it always has.

Why Your Decisions Shape Your Life?

People don’t choose their birthplace, family, school system, health, or the moment in history they’re born into. That randomness alone already shapes a lot.

But then, there’s the other side. The one thing we do control. Our decisions.

That’s where the conversation gets interesting.

Because even though we can’t remove luck from the equation, the quality of our decisions influences how we navigate it. How we respond. How we prepare for what’s next.

That’s where responsibility lives. Not in outcomes, but in process.

And it doesn’t stop in childhood. Luck still decides which team picks your CV, who crosses your path, which idea takes off.

It decides which day you meet the right person. Or the wrong one.

But none of that means we’re powerless. That’s where the second part comes in.

Even in a world full of randomness, you still make decisions on how to act. What to say. Where to focus. Who to trust. What risks taking or avoid. You decide (with your pack of decisions) how you treat people. How you show up.

And over time, those choices start to shape the way you walk through the world, and what the world sends back your way.

Now here’s where things get tricky. We often confuse good results with good decisions. And bad results with bad decisions. But that’s not how things work. If someone runs across a highway blindfolded and nothing happens, it doesn’t mean they made a smart choice.

It just means they were lucky. If someone carefully checks traffic and still gets hit, it doesn’t mean they did something wrong. It just means things don’t always go as planned.

That gap between choices and outcomes is what makes life so hard to understand sometimes.

Daniel Kahneman and others explain this in Noise. Their research shows how human decisions are full of inconsistency. Two people, same situation, different results. Even the same person, on different days, might make a different choice. And that’s without even getting into all the unknowns we deal with daily.

But here’s what I’ve learned from books like How to Decide, Thinking in Bets, and The Success Equation. You don’t have to control the outcome. You only have to improve how you make choices. The thinking before the doing. The reflection before the action.

That’s the part that compounds over time. Quietly. Without applause. The more you pay attention to how you decide, the better you become at noticing what’s worth your energy and what isn’t. You don’t need to be right all the time.

You just need to reduce the number of times you rush into something you regret. You learn to ask better questions. To pause. To say “I don’t know” when you don’t. That’s not weakness. That’s how stronger decisions start.

Imagine someone flipping a coin and saying heads means “take the job” and tails means “don’t.” That’s not a decision. That’s giving up the one thing you actually own. And yet, many people go through life reacting to noise, to pressure, to fear of missing out. When you start asking yourself, “Why am I doing this?” and “What could go wrong?” and “What don’t I know yet?”, you start walking with more intention.

And walking with intention matters. Because life will still surprise you. Luck will still hit you. But you’ll be ready. Not with the right answer every time, but with a way of thinking that helps you deal with whatever happens.

The dice are always rolling.

Some days you land on a good space. Other days you land on something that sets you back.

But what really changes the game is how you play between the rolls. What you learn. What you carry. How you choose to respond.

Some people keep rolling without ever thinking.

Others step back and start paying attention.

Not to the result, but to their own thinking. And that’s the difference. Not the outcome. The process behind it.

Over time, you’ll see people who got lucky and still ended up lost. And others who had every reason to quit, but didn’t. Not because life got easier. But because they make better decisions. Not once, but again and again.

So if there’s one habit worth building, it’s not trying to control the future. It’s learning how to make decisions today.

That’s what you get to own.

Not how the dice fall. But what you do next.
