As important as it is to think there are times when you have to be able to not think. When it is time to do something don’t think, just get up and do it.
When you think about the job ahead it gets overwhelming. The fact is that you don’t do the whole thing at once, you do it as you move along. When you are thinking about what you have to do, you are thinking of the whole thing at once, which is impossible and overwhelming.
