Oh man, that's a tough one! Like, imagine you're building a rocket, right? Technical stuff is like the fuel and the engineering that gets it off the ground. But psychology, dude, that's like the astronauts' mental game. If they're all stressed out or scared, it's game over. So, it's like a balance, ya know? Both are hella important. You can't have one without the other. It's like peanut butter and jelly ? they just go together!
