If you're going through hell, keep going.
If you can dream it, you can do it.
I can, therefore I am.
It's always too early to quit.
By failing to prepare, you are preparing to fail.
Begin to be now what you will be hereafter.
Know or listen to those who know.
Be kind whenever possible. It is always possible.
You never know what motivates you.
Always desire to learn something useful.
Fullness of knowledge always means some understanding of the depths of our ignorance and that is always conducive to humility and reverence.
