觉得很自卑.....

Yesterday got PE class,
and we did sit-ups, I only done 27, while other ppl do more than 35.....
Then, we measure our height and weight....
I only grown about 2cm, currently 151.5cm......so short......
then I already 51kg, while many ppl only about 37 to 47kg and not more than 50 T_T
Now I下定决心must exercise at least 3 times a week and go for either swimming or
badminton on Sundays....to lose weight.....
