Wherever you are - be all there.
The dog that trots about finds a bone.
If you're going through hell, keep going.
By failing to prepare, you are preparing to fail.
Always desire to learn something useful.
Leap, and the net will appear.
Expect problems and eat them for breakfast.
The secret of getting ahead is getting started.
Go for it now. The future is promised to no one.
Without hard work, nothing grows but weeds.
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.
