If you feel that the write program is bored, you can try to sell a month, maybe less than 3 days, I feel that I have written the program :) Actually, I think what to learn, I don't think about personal interest, I like the program, especially There is difficult, innovative. It feels that the process of encountering difficulties to solve is the most wonderful. If you always repeat what you have learned, the more you repeat, you will be annoyed. This is the reason why I am running, I think it is also one of the reasons for other friends to hop or stroke.
