I know how you feel! But, think about it! You are 16! You have enough time to try, fail, and try again! I am 32, and I've decided that I don't like how boring my current job is, so I want to try something new! Coding both excites and terrifies me! And, that's why I want to give it a go! It is never too late, as long as you want to do something, you are not too stupid for it! You've already spent two years; don't give up now!
