Iron Sharpens Iron!
There are 3 basic ways that we learn wisdom.
By Reflection, which is noblest
By Imitation, which is easiest.
By Experience, which is bitterest.
How have you learned your wisdom? What have you reflected on, what or who have you imitated? What experiences have you had that have propelled you forward with wisdom. Sometimes wisdom can be expensive, but lack of wisdom is always expensive!
