If you think you can do it, you can.
The wise does at once what the fool does at last.
Well done is better than well said.
Be kind whenever possible. It is always possible.
It's always too early to quit.
Problems are not stop signs, they are guidelines.
If you've got a talent, protect it.
Who seeks shall find.
Without hard work, nothing grows but weeds.
The secret of getting ahead is getting started.
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.
