Quality is not an act, it is a habit.
If you've got a talent, protect it.
If you're going through hell, keep going.
Without hard work, nothing grows but weeds.
What you do today can improve all your tomorrows.
Always desire to learn something useful.
If you think you can do it, you can.
It's always too early to quit.
Be gentle to all and stern with yourself.
You never know what motivates you.
Be thankful for problems. If they were less difficult, someone with less ability might have your job.
