I’m trying to write my will and I keep changing my mind.

A year ago. My understanding of what love is has changed immensely since.

I bought a house with someone and realised at the housewarming party that it was a mistake.

I am so obdurate I do not change my mind.

As an entrepreneur, I am the sort of person who prefers to understand things in an intuitive way and make top-down decisions. I have previously referred to the process by which I make decisions as a game of catch between my left and right brain.

I often take this advice and keep an eye on the ones the world may dismiss as crazy—Elon Musk included. They are often the ones who have the guts to take on a big project; The courage to be aggressive and innovative.

What I’ve come to realize is this: Optimism is more than just a feeling; it’s a strategic approach. And when navigating uncertainty, setbacks and change, it’s one of the most powerful tools in our arsenal.

My answer may have surprised some in attendance at the meeting: I don’t have a role model or sensei. Or to be more precise, I don’t have a single teacher. Instead, I take it upon myself to learn from everyone around me. If we open our eyes, we may find that everyone can be our teacher.

My “act first” process is not foolproof. It can result in mistakes. In other areas of my business, we’ve changed policies that drew criticism from our customers, launched services too early, and pursued acquisitions that failed to close. But I consider these necessary risks, taken in the pursuit of innovation. In business, there will always be ideas that fail and projects that disappoint. But we learn these things by acting.

We didn’t research the product. We didn’t launch a focus group or field a study. We had an idea, and we acted. The results informed our thinking.
