It's always too early to quit.
The wise does at once what the fool does at last.
Never complain and never explain.
Things do not happen. Things are made to happen.
Wherever you are - be all there.
Know or listen to those who know.
Always desire to learn something useful.
Begin to be now what you will be hereafter.
The most effective way to do it, is to do it.
The dog that trots about finds a bone.
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.
