If you're going through hell, keep going.
Expect problems and eat them for breakfast.
You never know what motivates you.
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.
By failing to prepare, you are preparing to fail.
After a storm comes a calm.
Leap, and the net will appear.
What you do today can improve all your tomorrows.
You will also allow me to thank the Academy for inviting me to lecture in Stockholm, for its hospitality, and for the opportunity afforded me for admiring the charm of your people and the beauty of your country.
