Who can help me ？

I don't know why I've (I have) become like this -  because I fonud that I change so lazy (I found that I have changed and become lazy). I don't like this life.
I can't find the any direction; I don't know how to solution solve so many things (or: I don't know the solution to many things).

Why do you feel like this?! If you realise you have become lazy, then change it! Pick up a new sport, a new language, or join a new club. Spend more time with friends and family. Don't waste time thinking about how lazy you are but do something about it :)

I don't think there is any one right direction. Anything that is right and makes you happy all leads to a great direction. Good luck! :) 加油！
