Thomas Edison on motivation and goals

I have not failed. I’ve just found 10,000 ways that won’t work.

There is no substitute for hard work.

Many of life’s failures are people who did not realize how close they were to success when they gave up.

A journey of a thousand miles begins with a single step.

Do, or do not. There is no ‘try.’

Never give in⁠—never, never, never, never, in nothing great or small, large or petty, never give in except to convictions of honour and good sense. Never yield to force; never yield to the apparently overwhelming might of the enemy.
