Yeah. You know how you're probably afraid of what other people will think if you do this or mess up at that, or whatever?

Just remember that every single person whom you're trying to look good in front of, is also trying to look good in front of you, or someone else.

Really think about what that means. You're spending all this time worrying what other people think about you, that you don't notice how many people have the exact same problem and aren't even thinking about that time you peed yourself for more than a few minutes.

Look at the posts on Seddit about confidence. Look a the entire r/amisexy subreddit. Look at the entire internet culture borne out of upvotes and downvotes.

You're not the only one worried about what other people think of you.

So, stop worrying about all that bullshit, and do what you need to do.

UPDATE

Expanded on this a bit.
