If you find things that amuse you then it wont be as boring you have to find a subject that you really enjoy or you will just look at it as being boring and you will never see the good that is learning something new if you hit the books hard instead of slowing down and doing a little more enjoying then you will never get through it. Look at it as an adventure and set goals such as what grade you think you can achieve and also how much you can learn and remember that may be useful in conversations later. You may suprise your self and others with how much you know.
Maybe you're just skimming by and not really challenging yourself? School is the difference in a great life with a career and a comfortable income. No school is loserville. Look at it that way. Try and do your best and make the best grades possible. There are always boring teachers, but many are excellent and if you really get involved, classes can be really exciting.
