if you 16 and in 12th grade u must be smart. Smart is good, education is good but without wisdom your life feels empty. your a normal young man lots of people your age don't know. when it comes to grades don't let it bother u most so called smart people have a better active memory so its easy to remember. u sound creative explore all the things you like to do including hobbies . Also the military has great benefits if you stay in 20 or so years . also college is so expensive that your almost better starting somewhere entry level and hope u can move up and sometimes they pay for u too go to school so explore all the possibilities good luck
