I've always been a curiosity-driven person. Leaning new knowledge or figuring out how to solve problems that are not well defined often gives me simple joy.
The fun part of being a cofounder is how it "forced" me to develop new perspectives on company strategies, team building (at the company level), and much more, as well as how these seemingly abstract terms are deeply connected with our day-to-day actions, planning and narratives.
With real-world experience, ideas that once felt theoretical become approachable and it is true for many terms in many domains.
