To know oneself, one should assert oneself.
Expect problems and eat them for breakfast.
Problems are not stop signs, they are guidelines.
Either you run the day or the day runs you.
What you do today can improve all your tomorrows.
Be kind whenever possible. It is always possible.
Know or listen to those who know.
Wherever you are - be all there.
Well done is better than well said.
Never complain and never explain.
I write in the morning from about eight till noon, and sometimes again a bit in the afternoon. In the morning I start off by going over what I had done the previous day, which my wife has happily typed up for me.
