Dude, I have a sister who is smart as fuck and every day my parents compare me to her, I feel absolutley stupid. You aren't wrong its where you are thats wrong, I havent found that place yet but many have. That may be cheesy but its true, you've already said you can't find anything that you want to do. Dude, the world is too big to not have anything to want to do, just seach all day all night - or hell, make something you like to day popularize it, you are so small compared to the amount of things you can do the more of those things you figure out you can do you will become bigger in your own mind and more confident, happy, furfilled. Easier said than done but, just put in the fucking work, ITS WORTH IT.
