We all know that to achieve any chosen goal, we must focus. The ability to concentrate is a skill of the highest value. To succeed at anything, you must be able to concentrate all your thoughts on the idea you’re working on. But don’t lose heart if, for now, you can’t hold your attention on a single thought for long enough. Very few people can do that.
It may seem rather strange, but we find it easier to focus on something harmful to us than on what benefits us. This tendency can be overcome by learning to consciously focus your attention on something.
