Can't do everything in life just by empirical patterns of actual experience from the past. Instead, need to think, look at how things work, find causes, reason, and plan. It's not about me. I should not use my resume as my primary evidence. But, yes, I've been in business, sometimes as a founder. As a founder, sometimes I made good money and sometimes not. Now I am a founder again and hope to 'go live' soon. And I have seen a lot of business founders over the years, some close and some distant, some with failures or with successes from small, medium, large, or extra large. I get my views partly from such observations. Just now in my work, I don't want a co-founder, and for essentially the reasons I gave: Dilute the direction and/or quality of the work, spend more money, and spend time in 'management'.
