If you've got a talent, protect it.
It's always too early to quit.
Things do not happen. Things are made to happen.
Without hard work, nothing grows but weeds.
Only the educated are free.
Be thine own palace, or the world's thy jail.
Be kind whenever possible. It is always possible.
Well done is better than well said.
You never know what motivates you.
Know or listen to those who know.
People are at their happiest if they are true to themselves. I think that applies to their chosen profession, friends and relationships. It goes for your health too. If you are true to yourself, it seems to me everything should work out pretty well.
