Here’s a fun website: Things Other People Accomplished When They Were Your Age
It’s a great way to depress yourself by comparing yourself to other people! Perhaps not good for your mental health, but maybe you can stop being so self-conscious and find it funny… and be sure to also look back at what other people accomplished before they were your age, just to rub it in.
It looks like the site’s author is also accepting achievement submissions from the common man, so sprinkled in with the famous accomplishments of famous people are some accomplishments you probably don’t care about. I’m not sure what the point of that is; perhaps it’s an effort to pull you out of depression?
And you’ll see on that page there’s a link to Help for the Attitudinally Challenged, which might help if you now feel miserable.
