If you're going through hell, keep going.
I can, therefore I am.
Problems are not stop signs, they are guidelines.
Do not weep do not wax indignant. Understand.
You never know what motivates you.
Be gentle to all and stern with yourself.
Be thine own palace, or the world's thy jail.
What you do today can improve all your tomorrows.
Begin to be now what you will be hereafter.
If you've got a talent, protect it.
The learner always begins by finding fault, but the scholar sees the positive merit in everything.
Mere goodness can achieve little against the power of nature.
Truth in philosophy means that concept and external reality correspond.
