how could i be the best possible me

Hi alabaz, Do not get upset.First look for the factors that poses an impediment to your being the best.Like may be you can't remember what you have studied at the time of exam.It means that you've to spend more time with your studies and you require application of your brain.I've seen student of high school who do not sleep much.They are always engaged either in library or with some project work.They make the plan to make something new or they just scavenge the old much acclaimed works.And do not compare yourself with others because you don't know what margin you've.Set your objective and work hard.Be focussed and don't look anywhere except for your goal.
