Quoting:
"Developers are not CTOs. I remember an argument I heard from a single developer CTO. He’d say stuff like, “Well I made the product, and I was here when it started so I’m the best fit for CTO.” That was me, a decade ago. Wow, was I ignorant.
What if we extend that logic to other parts of life? “Well, I was standing next to him when he had a heart attack, and I make medical equipment, so I’m the best one to do the triple bypass.” Laughable. If I rest on past achievements I’ll never grow."
