Wisdom is knowing. Skill is know how to do it. Virtue is doing it.
Whatever you attempt, go at it with spirit.
To say no at the right time, and then stand by it, is the first element of success. He is the wise man who, for all his life, can keep mind and soul and body clean.
The problem of life is not to make life easier, but to make men stronger.
Wisdom is knowing what to do next; virtue is doing it.
There is no pleasure in life equal to that of the conquest of a vicious habit.
