Don't be afraid to take an unfamiliar path.  Sometimes they're the ones that lead you to the best places.

There is no elevator to success, you have to take the stairs.

A hero is no braver than an ordinary man, but he is braver five minutes longer.

The easiest person to deceive is yourself.

Pure mathematics is in its way, the poetry of logical ideas.

Success is the sum of small repeated efforts, day in and day out.

Don’t confuse your path with your destination. Just because its stormy now doesn’t mean you are headed for failure.
