I am in a phase of massive procrastination. I feel I cannot concentrate on my work. When I start doing my work, some minutes later I will feel uneasy and tired. I have no problem doing other tasks though, for example computer programming, but nobody needs it.

Is it that a task has to be stimulating enough for me not to fall asleep?

Or maybe am I just anxious and avoiding tasks that I have to do because I might fail?
