I didn't . Then again I'm a guy. Do whatever you want it's your locker. It's not like everyone is going to stop by your locker and comment on how uncool it is . It's your locker if its cool to you it's cool period .
not at all, I honestly don't think you'll have enough time to sit there putting random things on your locker, I would just put up a mirror or a little whiteboard so that you can write due dates and stuff on it
Kind of. It is just a book and personal item depository. Why would you need decorations? It is a waste of money. Nothing wrong with organizational stuff but... a picture of Justin Beiber would only help keep you from getting roaches in your locker.
No fuck them. Whilst you have your young mind that pays attention to all the colors of this world hold on to it and do not let thoughts literally just a voice in your mind (which is actually the voice of your friends/people around you) worrying you putting you down in the hierarchy wanting to fit in and all that essentially negative bs. Just do it but if you want to feel comfortable too then get other people to do it and be ready to like back up people who are negative and try and call something original like that 'stupid' or something that their dull minds think of. I may have overanalysed your question lol.
