In a coaching session a person told me he lacked self-confidence. I asked him if he had no confidence in anything he does in life, like in sports, a hobby, in driving a cars or whatever. After reflecting he admitted he had lots of confidence in his jogging ability! So he has confidence, just not in all areas. So the challenge is not to create confidence, it is to move it a bit and expand into other areas of your life, which is a very different task. Next time you think about your missing a certain trait, look inside yourself for a while before you conclude that the thing is not there at all!
