Concentration and self-descipline are the most precious wealth to person. I realise that when I am nearly forty. What I did is not bad, because I can focus on one thing. What I did is no good enough, because I can't concentrate more on the most important thing. I am always disturbed by something else. I am so lazy, I am not work hard. I should have done all of things better, more efficiently, but I have not. If I have concentrated more on my study and career, I would get more.
