Confidence is like a helpful virus spreading throughout your body.
If you have it, it will infect everything you do in a positive way. If
you don’t, it will undermine everything you do.
People who lack confidence not only fear doing things they are
not good at, they actually start to fear performing tasks in which
they excel because they question whether they’re all that good at
Confidence spreads with successes, and lack of confidence multiplies
with failures. If your confidence falters, turn to what you do
best, and then take on more challenging tasks. Build little daily successes
to increase it.
