Optimism in the face of uncertainty can minimize regret and help you avoid looking back with disappointment.

The delta between expectations and reality is a significant factor in unhappiness. It's easier to manage expectations than to change reality, so setting clear expectations is crucial for both customers and internal stakeholders.

It's beneficial to have a nuanced understanding of how hard it is to build something successful. Sometimes, underestimating the difficulty can be helpful, but be cautious of flipping into a negative mindset when challenges arise.

Expect that on any given day, two bad things and two good things will happen; it's important to manage stress and maintain perspective.

The worst-case scenario isn't as bad as you think; if you take a risk and it doesn't work out, you can always find another job.

If you're too pessimistic, you might give up too early or expect things to be easier than they are, which can drain the energy of those around you.

Sometimes, it's valuable to embrace uncertainty and allow for surprises in life, rather than over-researching and planning every detail.

It's important to explicitly discuss and understand the worst-case scenarios of taking risks, as this can help alleviate fear and clarify your options.

It's important to maintain a general optimism about the future while being skeptical of specific opportunities, as this balance can help navigate the uncertainties of life.
