Never complain and never explain.
Things do not happen. Things are made to happen.
Know or listen to those who know.
The secret of getting ahead is getting started.
The most effective way to do it, is to do it.
Be kind whenever possible. It is always possible.
You never know what motivates you.
By failing to prepare, you are preparing to fail.
Well done is better than well said.
The dog that trots about finds a bone.
People who have time on their hands will inevitably waste the time of people who have work to do.
