Serious or not

ok the problem has been bugging me for sometime. I feel that maybe sometimes just sometimes i am too nice to ppl. ppl suan me i keep quite not because i afraid of u its i feel is let it be whats the point? but thats not the main issue. the problem is that i am never really serious on things, study half way can on dota play lol. I noe what i can do and what i am capable but problem is i am never serious enough to do it properly. Hiaz what to do maybe i really dun hav enough discipline
