The Power of Positive Thinking

and this isn’t just some crazy new age idea, it was embraced by Gandhi.

Man often becomes what he believes himself to be. If I keep on saying to myself that I cannot do a certain thing, it is possible that I may end by really becoming incapable of doing it. On the contrary, if I shall have the belief that I can do it, I shall surely acquire the capacity to do it, even if I may not have it at the beginning.

Gandhi
