Get as many rejections as possible. Show up and shoot your shot. You already have the no.
Ask for things. Ask for things that feel unreasonable, to make sure your intuitions about what’s reasonable are accurate (of course, try not to be a jerk in the process). If you’re only asking for things you get, you’re not aiming high enough. Jobs are a great example: Particularly if you’re early in your career, you should aim to get rejected from most things you apply for. If you have not yet learned the skill of absorbing rejection, court it deliberately: Apply for some jobs you really don’t think you’ll get so you can learn to decouple “no” from surprise and dejection.
