To know oneself, one should assert oneself.
Quality is not an act, it is a habit.
Expect problems and eat them for breakfast.
Without hard work, nothing grows but weeds.
If you think you can do it, you can.
Do not weep do not wax indignant. Understand.
Problems are not stop signs, they are guidelines.
The most effective way to do it, is to do it.
Things do not happen. Things are made to happen.
Never complain and never explain.
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.
