sadness

There is no reason that I am rather sad. I fail to concentrate on work. I wish time flies swiftly so that I couldn't suffer the fighting of thinking.
With the change of life envrionment, i become more and more frustrated. I could't control my feeling and thinking. How can I throw away the bad habits? I couldn't deny that I am a diligent and ambitous girl. However, most of things noly keep basic stage, only in the low level. In other words, I can plan my future and my life, but it's difficult for me to carry out these in terms of my plan.
Anyone can forecast the not distant future. It's essential to live in current. Change my attitude towards life and enjoy life.
