Be gentle to all and stern with yourself.
Things do not happen. Things are made to happen.
By failing to prepare, you are preparing to fail.
Be kind whenever possible. It is always possible.
The secret of getting ahead is getting started.
It's always too early to quit.
Well done is better than well said.
To know oneself, one should assert oneself.
Expect problems and eat them for breakfast.
Begin to be now what you will be hereafter.
Living with the immediacy of death helps you sort out your priorities in life. It helps you to live a less trivial life.
