When one is strong - he should appear weak.
But the majority of people work harder on appearing strong than they do on actually being strong.
If wisdom comes from sorrow then strength must come from difficulty or opposition.
It seems that no one wants to face failure - so, few make an effort in any thing.
Few have done the groundwork which would enable him to support his success if it ever came.
Humility takes effort... and focus.
One must focus on his goal and not on all the accolades or criticisms of others.
One must focus on his vision even when others show doubt.
"Faith", "Knowledge", "Confidence" and "Humility" - while they may not be synonymous, they do seem to be interwoven.
