It takes courage to achieve something because you have to start it in the first place.
What if you had to jump off a diving board from a high level to win a bet? Or maybe sing or give a speech in front of a huge crowd if you were afraid of speaking in public? Getting good grades, graduating, asking a crush out.
All of these things are possible to accomplish, yet you need courage to achieve them because it’s scary to start if you’re afraid you might fail. You need courage to achieve them because of how hard it may get in the process.
