There's a real psychological trigger that flips people from watching the sidelines to actually jumping in. It's not about waiting for guaranteed wins—most successful people don't operate that way. They're answering something much more basic: do I have enough reason to move, or not? The gap between certainty and action is smaller than you'd think. You don't need absolute proof. A lot of market participants act when they hit that sweet spot—just enough confirmation signals aligned, just enough conviction to pull the trigger. Perfect certainty? That rarely shows up before the move happens anyway. The ones hesitating for 100% proof usually miss the window entirely.
