If i could turn back time, what would do

If i could turn back time, many a lot of thing i want to change. Before that, many thing i am not satisfy with what i have done. first thing that i want change is my study at secondary,primary school. I want get a best result for each examination subject, if that time i get a best result i will go to the better University right now. that also i can prove to family i can do it! same like my brother success in his study

sometimes i always make some mistake in my routine life, from that i would like to redeem my own mistake and make my best thing that i could not done. For a better routine life i will create my schedule time table for my daily day. This will make me doing a good thing and also make me good time management person
