Optimism doesn’t come naturally, not as naturally as pessimism and doubt, at least.
If you’re pessimistic, everything is a roadblock. When something does go wrong, you’re quick to pull a “see! I told you so!” and feel validated in your concern. It’s a low-risk life, but one fraught with stress about a million things that never actually happen.
Optimistic people are the ones who build things and see the future as bright and something worth investing in. They believe it deeply enough to invest time, energy, and money into building something for the future.
Problems will arise, but it’s an opportunity to innovate, streamline, and make your project more robust and anti-fragile.
We’d all be a bit better off if we remembered that pessimism is easy but usually destructive. On the other hand, optimism is difficult but will usually help us to be very productive.
