Things do not happen. Things are made to happen.
It's always too early to quit.
Either you run the day or the day runs you.
Wherever you are - be all there.
Without hard work, nothing grows but weeds.
Quality is not an act, it is a habit.
To be a good loser is to learn how to win.
After a storm comes a calm.
Problems are not stop signs, they are guidelines.
Always desire to learn something useful.
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.
