You never know what motivates you.
Never complain and never explain.
Wherever you are - be all there.
To be a good loser is to learn how to win.
If you're going through hell, keep going.
If you've got a talent, protect it.
After a storm comes a calm.
Either you run the day or the day runs you.
Always desire to learn something useful.
Only the educated are free.
The diversity of the phenomena of nature is so great, and the treasures hidden in the heavens so rich, precisely in order that the human mind shall never be lacking in fresh nourishment.
