Motivation is a fire from within. If someone else tries to light that fire under you, chances are it will burn very briefly.

Motivation is the fuel, necessary to keep the human engine running.

Motivation is a set of emotions (painful and pleasurable) that act as the fuel for our actions.

Motivation is crap. Motivation comes and goes. When you are driven, whatever is in front of you will get destroyed

A burning sense of passion is the most potent fuel for your dreams.

Without inspiration the best powers of the mind remain dormant. There is a fuel in us which needs to be ignited with sparks.

Organisms need, to use the metaphor of Marcus Aurelius, to turn obstacles into fuel — just as fire does.

"You know what I think?" she says. "That people's memories are maybe the fuel they burn to stay alive. Whether those memories have any actual importance or not, it doesn't matter as far as the maintenance of life is concerned. They're all just fuel. Advertising fillers in the newspaper, philosophy books, dirty pictures in a magazine, a bundle of ten-thousand-yen bills: when you feed 'em to the fire, they're all just paper. The fire isn't thinking 'Oh, this is Kant,' or 'Oh, this is the Yomiuri evening edition,' or 'Nice tits,' while it burns. To the fire, they're nothing but scraps of paper. It's the exact same thing. Important memories, not-so-important memories, totally useless memories: there's no distinction — they're all just fuel."

You don’t need to choose mediocrity when fire exists. Fire is passion and passion is aliveness, and for once, allow your belief to undo your disbelief so destiny can hold you in its ecstatic, flaming grasp.

Life is like a flame that is always burning itself out...

The fuel on which science runs is ignorance. Science is like a hungry furnace that must be fed logs from the forests of ignorance that surround us. In the process, the clearing we call knowledge expands, but the more it expands, the longer its perimeter and the more ignorance comes into view.

Love lives on hope, and dies when hope is dead;
It is a flame which sinks for lack of fuel.

Goals are the fuel in the furnace of achievement.

Encouragement is the fuel on which hope runs.
