If you believe in something, you need to go for it and don't quit just because the glass half empty folks say it won't work!

I prefer to think in terms of a half full gas tank. If you need 3/4 of a tank full to get where you're going you'd better make some plans for the other 1/4 if you start out with only half a tank. Optimism by itself won't fill the tank, money and filling stations are going to be required.

That is why you start with optimism and throw in hard work to achieve your goal -- don't quit when there are roadblocks thrown in your way but keep on pushing ahead!

Agreed. But how many pessimists raise money and build filling stations?
