It's always too early to quit.
Well done is better than well said.
The most effective way to do it, is to do it.
Problems are not stop signs, they are guidelines.
Without hard work, nothing grows but weeds.
I can, therefore I am.
If you've got a talent, protect it.
Be gentle to all and stern with yourself.
Only the educated are free.
Go for it now. The future is promised to no one.
Fullness of knowledge always means some understanding of the depths of our ignorance and that is always conducive to humility and reverence.
