It's always too early to quit.
Begin to be now what you will be hereafter.
Know or listen to those who know.
Without hard work, nothing grows but weeds.
If you think you can do it, you can.
Wherever you are - be all there.
Be gentle to all and stern with yourself.
If you can dream it, you can do it.
Expect problems and eat them for breakfast.
If you're going through hell, keep going.
No amount of study or learning will make a man a leader unless he has the natural qualities of one.
