To know oneself, one should assert oneself.
Without hard work, nothing grows but weeds.
Never complain and never explain.
Well done is better than well said.
If you've got a talent, protect it.
If you think you can do it, you can.
Know or listen to those who know.
Go for it now. The future is promised to no one.
The wise does at once what the fool does at last.
It's always too early to quit.
The work is with me when I wake up in the morning it is with me while I eat my breakfast in bed and run through the newspaper, while I shave and bathe and dress.
