Be gentle to all and stern with yourself.
Things do not happen. Things are made to happen.
It's always too early to quit.
Always desire to learn something useful.

If you've got a talent, protect it.
Be kind whenever possible. It is always possible.
Wherever you are - be all there.
Without hard work, nothing grows but weeds.
You never know what motivates you.
