Avoid negative people. They have a problem with every solution.

Doubt that drains versus doubt that sharpens

We all know that person—the one who shoots down ideas before you've even finished explaining them. But here's what makes this advice tricky: sometimes the "negative person" is actually being careful, not just cynical. There's a real difference between someone who questions thoughtfully and someone who reflexively dismisses everything. The problem isn't skepticism itself; it's when someone treats objection as a substitute for thinking.

The real insight is about energy drain. Negative people don't just disagree—they exhaust you by making solutions feel impossible before you've even tried them. They're not problem-solvers; they're problem-dwellers. And the thing is, this attitude is contagious. Spend enough time around it, and you start believing obstacles are bigger than they actually are. You second-guess yourself before you take risks.

That said, completely avoiding all critical voices leaves you naive. The move is to distinguish between people who challenge you to think deeper and people who simply drain your hope. Surround yourself with people who ask hard questions but still believe things can work. That's where real progress happens.
