If you make a decision and the outcome is good, you'll be closer to your goals. If you make a decision and the outcome is bad, you might be temporarily worse off, but you'll learn something for the next decision.
Sometimes people think they can avoid a bad outcome by avoiding the decision entirely. But the world doesn't stop just because you do. At best, indecision leaves you with stress and wasted time. At worst, it'll also leave you with regret and a bad outcome anyway.
"In a moment of decision, the best thing you can do is the right thing to do, the next best thing is the wrong thing, and the worst thing you can do is nothing." - Theodore Roosevelt
