The most effective way to do it, is to do it.
If you think you can do it, you can.
What you do today can improve all your tomorrows.
Begin to be now what you will be hereafter.
You never know what motivates you.
Leap, and the net will appear.
Know or listen to those who know.
After a storm comes a calm.
If you've got a talent, protect it.
Always desire to learn something useful.
