I am perfect....Or am I ?

Well everybody isn't perfect but something that I really should change about myself, is how good my grades are because usually I get C's and sometimes my grades aren't at that level.  I should change that thing because grades are really important, in school especially if your playing any sports. I will be a better person if I change my grades because I will have more success in school this year.  The only people that know about my grades are me and my family and maybe a couple of friends. Grades are always, always important no matter what.
