"A man must be big enough to admit his mistakes, smart enough to profit from them, and strong enough to correct them" John Maxwell
True wisdom can only be gained by intentionally applying knowledge, experience, understanding, common sense and insight to your future thoughts, emotions and actions.
If we are to develop wisdom in everything, we must believe trials and stress have as much purpose as intentional learning and actions. Seeing life through opportunistic eyes means finding order in chaos, use in the useless, and good in the bad.
"In short, wisdom is a disposition to find the truth coupled with an optimum judgement as to what actions should be taken." From Wikipedia, the free encyclopedia
