However, when despite putting efforts we fail to achieve our goal due to other extrinsic or intrinsic factors that were associated with the achievement of goal, it acts as an threat to our self confidence. Self confidence is an integral and quite important part of our motivation and preparation and thus it can be restored with practice.
