How to cure anxiety

I am always very anxious about time.Sometimes I would stared at the watch for a while without doing nothing because I just wanted to know when the time is and how much time I left to finish my task.

I know the reason that I stared at the watch is sometimes I was very anxious about the task.I thought I didn't have enough time to finish my task. I thought the time was going too fast that I almost hadn't utilized it very well.The more I thought the time left was not enough,the more anxious I was.The more anxious I was,the more inefficient my work was.

But how can I solve this problem? Frankly speaking I have no idea.I don't know how to cure the anxiety.

Maybe a little anxieties are necessary for our life.So what I can do is learn to adjust myself.Try my best to shift my attentiion from the time to the task.Maybe I can do this.
