If you think you can do it, you can.
You never know what motivates you.
Without hard work, nothing grows but weeds.
Be gentle to all and stern with yourself.
Well done is better than well said.
Know or listen to those who know.
If you're going through hell, keep going.
The wise does at once what the fool does at last.
The most effective way to do it, is to do it.
Never complain and never explain.
Good judgement comes from experience. Experience comes from bad judgement.
