It's always too early to quit.
Problems are not stop signs, they are guidelines.
To be a good loser is to learn how to win.
The most effective way to do it, is to do it.
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.
The wise does at once what the fool does at last.
Quality is not an act, it is a habit.
I can, therefore I am.
There are no dreams too large, no innovation unimaginable and no frontiers beyond our reach.
