Things do not happen. Things are made to happen.
Either you run the day or the day runs you.
By failing to prepare, you are preparing to fail.
The dog that trots about finds a bone.
What you do today can improve all your tomorrows.
Know or listen to those who know.
If you're going through hell, keep going.
Be thine own palace, or the world's thy jail.
You never know what motivates you.
Well done is better than well said.
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.
