Always desire to learn something useful.
The dog that trots about finds a bone.
Either you run the day or the day runs you.
Know or listen to those who know.
If you can dream it, you can do it.
Begin to be now what you will be hereafter.
It's always too early to quit.
What you do today can improve all your tomorrows.
Problems are not stop signs, they are guidelines.
After a storm comes a calm.
I spent every night until four in the morning on my dissertation, until I came to the point when I could not write another word, not even the next letter. I went to bed. Eight o'clock the next morning I was up writing again.
