Be gentle to all and stern with yourself.
Wherever you are - be all there.
Never complain and never explain.
Begin to be now what you will be hereafter.
To know oneself, one should assert oneself.
Without hard work, nothing grows but weeds.
It's always too early to quit.
Know or listen to those who know.
Expect problems and eat them for breakfast.
What you do today can improve all your tomorrows.
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.
