If you've learned anything on these forums about yourself, others, or this blue planet, then you are far ahead of many of your classmates.
At 16, 75% of everything you do is going to be wrong-either for you or someone else. That's almost the definition of being a teenager. But don't fret the small stuff, just keep learning and growing. By the time you are 18, only 70% of everything you do will be wrong. 😛 (I'm 57, and 70% of everything I do is wrong. Just ask all the right wing Republicans on this board. 🙂 )
Don't compare yourself to anyone else, but DO try to learn from the few mistakes you've made. And nothing you've posted is cast in stone. You can kill your words, even after the fact! Gotta love that "update" button!
Before you post anything in the future, just give it a second or third thought. Edit your own posts before you hit the send button.
Good luck, whatever you decide to do.
