It's always too early to quit.
Without hard work, nothing grows but weeds.
If you think you can do it, you can.
To be a good loser is to learn how to win.
Begin to be now what you will be hereafter.
Leap, and the net will appear.
Know or listen to those who know.
Never complain and never explain.
The wise does at once what the fool does at last.
Problems are not stop signs, they are guidelines.
Ignorance of what real learning is, and a consequent suspicion of it materialism, and a consequent intellectual laxity, both of these have done destructive work in the colleges.
