Did you ever experience these two feelings?
- You try something (usually new), and by the looks of it, even before you try doing it, you have confidence that you can do it. You are convinced you are better than most people at it (even though you never tried it before). Many times you are right.
- You are about to do something you feel won't go right. You think that most people are somehow better at it than you. You try it, and mostly your prediction of failure comes true.
I'm sure these happen to all of us multiple times throughout our lives. In different areas and activities.
Sometimes though, things do not come out as we expect them to. We either expect to do well and don't or expect to fail and somehow manage to succeed.
On the continuum that exists between "I know I can do it" and "I know I can't do it," there is a broad middle ground, where we have a certain amount of confidence (or doubt).
In each case, our confidence is leaning to one end of the continuum, but the reality is somewhat away to the other side of the continuum.
Having confidence can help us only when it adheres to reality, and the same is valid for having (and eliminating) doubt.
High achievement lies in pushing confidence as far as it can go away from actual capability, while still maintaining a grip on reality. That is when you maximize your abilities.
