A good objective of leadership is to help those who are doing poorly to do well and to help those who are doing well to do even better.
Work harder on yourself than you do on your job.
The ultimate reason for setting goals is to entice you to become the person it takes to achieve them.
You are the average of the five people you spend the most time with.
Let others lead small lives, but not you. Let others argue over small things, but not you. Let others cry over small hurts, but not you. Let others leave their future in someone else's hands, but not you.
If you don't like how things are, change it! You're not a tree.
