Their doubt is your fuel for dreams. You just have to drive.

One needs to pursue some sort of a creative interest in order to keep life from eating us alive.

Rightly onward, pursue your dreams.

If at the one moment in your life when the chance of something transcendental is offered to you, if you have this chance to move beyond the surface of things, to understand - and you say, No, maybe not... What then? How do you explain the rest of your life to yourself? How do you pass the time until you die? Do you substitute for that an interest in what - eating? Do you spend the next sixty years trying to be fascinated by the act of breathing?

You can only achieve GREATNESS when you pursue the things others are not willing to SACRIFICE for.

You have to keep going and pursue your dreams.
