If you don't have a tonne of optimism, you're not going to make it... you won't be able to evangelise to everyone else. On the other hand, if you aren't constantly paranoid about what can go wrong and put plans in place, then you're going to get bitten at some point.
Most of us have to spend a lot of energy to learn how to drive a car. Then we have to spend the rest of our lives over-concentrating as we drive and text and eat a burrito and put on makeup. As a result, 30,000 people die every year in a car accident in the U.S.

When you attack a problem as though it were solvable, even though you don't know how to solve it, you will be shocked with what you come up with. It's 100 times more worth it. It's never 100 times harder.
It comes up over and over and over again that a ten times increase in the weight-oriented density of batteries or the volume metric, the space-oriented density of batteries, would enable so many other moonshots that that's one that just constantly comes up over and over again, and we will start that moonshot if we can find a great idea.
Really great entrepreneurs have this very special mix of unstoppable optimism and scathing paranoia.
