 No one is immune to the effects of pressure. It's simply not possible. Those who succeed in high stress situations, like musicians and athletes, have just trained themselves to be less affected by it. In pressure situations, they are better than others at performing as they normally would. Elite athletes like Serena Williams, LeBron James, and Tom Brady feel pressured just as we all do. But they have learned how to manage the feeling of pressure in their response to it. Michael Jordan had 25 game winners in his career, 24 of which came with less than 10 seconds on the clock. The only other player in the conversation as the GOAT, LeBron James, leads in a similar statistic. LeBron also leads all NBA players in game time or go-ahead shots in the final possession. These players' almost supernatural ability to sink difficult shots with all eyes on them comes from the way they have adapted to the pressure. Watch videos of Jordan's and LeBron's game winners, and you can see it in their approach coming out of the timeout. In their face as they catch the ball, in their movements as they release, they are assured as much as they can, they're going to treat it like just another shot. That's why it goes in.
