Wasting Time

I really think that I am wasting time in school. Why am I studying something I am not even interested in? I'm seriously wasting time. The school wants us to attend school, but yet when I'm in lecture, I'm not even paying attention to the lecturer, so what? Wasting my TIME! I want to make full use of time. I'm going to learn more things. Going to practise my piano. Gonna learn my japanese. Gonna start exercising. Gonna stop wasting time.
