The secret of getting ahead is getting started.
Without hard work, nothing grows but weeds.
The wise does at once what the fool does at last.
The dog that trots about finds a bone.
Things do not happen. Things are made to happen.
It's always too early to quit.
If you think you can do it, you can.
Be gentle to all and stern with yourself.
By failing to prepare, you are preparing to fail.
Always desire to learn something useful.

You see, I became kind of a drop-out in science after I came back to America.
