"Your job as CEO is not to advise other entrepreneurs..."
Wow. What a sad comment to read. Being a CEO means being a leader, and not just of those that work for you, but to serve as a leader and thus guide others that are trying to trek the same path you've taken (and might re-take).
I am speaking from experience. I once co-founded a company, now-defunct, and while serving as president of the company, was a formal advisor to another company. I think I provided a lot of value to the other company, and I absolutely learned from the experience.
However, in retrospect, I concluded that serving as an advisor to another company while I was building a new company of my own was not a good decision. Did taking the time to advise another company have a material impact on the outcome for my company? I don't believe so, but I can never know either. And that's the thing: when you start a business, win or lose you should always put yourself in a position where you can look back and know that 100% of the hours you made available to your work life were dedicated to the right effort.
