Always desire to learn something useful.
You never know what motivates you.
Go for it now. The future is promised to no one.
I can, therefore I am.
Know or listen to those who know.
If you think you can do it, you can.
Things do not happen. Things are made to happen.
Wherever you are - be all there.
It's always too early to quit.
Be gentle to all and stern with yourself.
It is in vain to hope to please all alike. Let a man stand with his face in what direction he will, he must necessarily turn his back on one half of the world.
