Never complain and never explain.
By failing to prepare, you are preparing to fail.
Without hard work, nothing grows but weeds.
Who seeks shall find.
It's always too early to quit.
Begin to be now what you will be hereafter.
Things do not happen. Things are made to happen.
The dog that trots about finds a bone.
Either you run the day or the day runs you.
Be thine own palace, or the world's thy jail.
The most useful form of time travel would be to go back a year or two and rectify the mistakes we made.
