Be kind whenever possible. It is always possible.
Things do not happen. Things are made to happen.
Without hard work, nothing grows but weeds.
What you do today can improve all your tomorrows.
Well done is better than well said.
If you're going through hell, keep going.
The secret of getting ahead is getting started.
Either you run the day or the day runs you.
The wise does at once what the fool does at last.
Know or listen to those who know.
I guess happiness is not a state you want to be in all the time.
