I used to think that being happy in time is the most important thing in life. Now I have changed my mind. Maybe self-discipline is more import than short-term happiness. I often read online novels and surf on social network to find freshness, but I always feel depressed when I put down the cellphone. In contrast, learning new knowledge or sleeping early really makes me feel happy and satisfied for a long time. Self-discipline set me free from idleness and modern technology which is designed to attract more attention.

There are 2 hours left until I am 24. I still have a lot of plans not implemented. Time flies. But this year is also my lucky year because I finally found where is my passion and which career I would pursue for my life. All I have to do is keeping self-discipline and chasing my dream in the age of 24.
