Watch Tsitsipas serve down match point. He doesn't rush. He bounces the ball, breathes, resets. That's not calm. That's a guy managing fear in real time. You're not lazy. You're scared. Scared the plan fails, scared people watch you try and fall short. So you scroll instead. You reorganize your desk instead. Anything but the thing that actually matters. Here's what changed for me: discipline isn't about feeling ready. It's doing the rep while you're still terrified. He doesn't wait for confidence. He serves anyway. Stop waiting to feel brave. Move scared. That's the whole skill.
