Two Kinds of Hardship
One kind: you're working on something hard, and it's hard because it matters. Because it's challenging. Because the outcome isn't obvious. That's productive hardship. You learn. You grow. You come out stronger.
Other kind: you're in a situation that's destructive. Toxic people. Impossible constraints. Work that doesn't matter. You can't win here. You're just enduring.
The Important Distinction
One type of hardship you move through. You accept the struggle because the destination matters. The other type you need to move away from. Not because you're weak. Because no amount of effort changes the fundamental situation.
Most people can't tell the difference. So they endure situations they should leave. Or they leave situations they should have pushed through.
How to Decide
Ask: if this hardship ends, will I have learned something? Will I have built something? Will I respect myself for having gone through it? If yes, stay. Push. The difficulty is the point.
If no — if you're just absorbing punishment with no outcome on the other side — that's not resilience. That's just staying too long.
The strongest people aren't the ones who endure the most. They're the ones who know which struggles are worth it.
