The world will always focus on the negative, that is why you must always focus on the positive. Nobody is going to tell you all things right that you are doing, instead your critiques will be criticisms. Its never a biased opinion, the feedback you get from the battling outside world, its slightly skewed towards that catch 22.
You remind yourself every night and right in the morning the light behind your eyes and the perception of personal greatness. You locate the strength behind your soul, and you face the long swim upstream once again.
Find the balance, humility v ego. This is where confidence comes from. To be assured that you can deal with an array of situations, whichever stumbles your way. Confidence is not letting the negative drag you down, not letting your horse get too high off the ground.
