[syllogism]

How could anyone provide a helpful answer to this?

If you have a dozen bad ideas before breakfast, your self-skepticism is really good! It's preventing you from spending time on ideas that are flawed. On the other hand if the ideas aren't bad, you're missing good opportunities.

The problem is to have better ideas, and be better at evaluating ideas. It's not a mindset problem of being more or less pessimistic or optimistic.
