That's true, but some people just don't have a high level of self-confidence to do what they want to do. They sometimes just need an extra push from their friends and the people around them.

[ naegi kind of knows that himself... but also from some of his friends ]

I actually really like the anime that you're referring to. It's pretty good! And it has a main character who has to learn to stand up for himself and be stronger. You might enjoy it.
