All of these tortured me in that I dislike that kind of self and life.

I realized that it is high time that I should change myself. Hence, I decided to establish a goal and made a plan. I found that little change made a difference because my life recover vitality.</div><div>So, today, do you complain about something? Do you start to change?</div>
