Choking

Confidence is generally described as a state of being certain, either that a hypothesis or prediction is correct, or that a chosen course of action is the best or most effective given the circumstances.

Self-confidence is having confidence in oneself when considering a capability.

Confidence can be a self-fulfilling prophecy, as those without it may fail or not try because they lack it, and those with it may succeed because they have it, rather than because of an innate ability.

Choking refers to losing confidence, especially self-confidence, just at the moment when it is needed most and doing poorly as a result

Its a real lousy feeling you can't control or shake off..I know coz I choke all the time ..=( What doesn't change on the inside will affect what appears on the outside i guess..Time for a huge huge PARADIGM SHIFT!
