It's always too early to quit.
Things do not happen. Things are made to happen.
If you're going through hell, keep going.
Either you run the day or the day runs you.
Without hard work, nothing grows but weeds.
Go for it now. The future is promised to no one.
Quality is not an act, it is a habit.
Always desire to learn something useful.
If you think you can do it, you can.
Know or listen to those who know.
A hatred of failure has always been part of my nature.
My formula for success is rise early, work late, and strike oil.
