I interpreted that as concerning two different domains with respect to a Start Up (or any immature business, really).
With respect to stability: Persons with lots of frequently changing variables in their lives (e.g. frequent beginnings/endings to relationships, moving around, etc.) have less stability. Adding the instability that comes with a turbulent, chaotic tech start up just compounds the issue and taxes one's resilience even more, because inevitably one will have to pay attention to instabilities other than business related ones.
With respect to responsibility: having kids, a spouse and other similar obligations (can) act as a tether and definitely act as dividers of attention. A spouse and children necessarily require attention that could otherwise be focused on the business. This is really much more of a problem for individuals who aren't already financially secure and depend on some relatively secure, stable income to support their lives.
The common element in both cases is time and attention: living an unstable life increases the probability of something other than the business acting as competition for attention, and living a life with other responsibilities "baked in" guarantees competition for attention.
If your spouse is a source of drama, chaos, and fights, then it will detract from your startup goals. If your spouse is highly supportive, hard working, and believes in your startup, then it will assist your startup goals.
If you're single and have a reasonable social life, it can add to your startup goals. If you're single and out closing down the bar every night, then it will subtract from your startup goals.
I think the point is that people without 'life responsibility' find it easier to have a 'stable' life. E.g. When you don't have a wife and kids to care for and spend time with the balancing act you have to maintain to have a stable life is much easier.
I'm not convinced thats a contradiction. Being single does allow for you to kind of.. put relationships on hold for awhile to push hard for your business. I'm not sure thats wise in general, but it seems advantageous in certain scenarios.
- The more stability the rest of your life has, the easier it’ll be to deal with the massive instability of a startup
- People without life responsibility (kids, wife, etc) are at a serious advantage in the beginning stages
So what would your conclusion be here? Are people with stable love-life in advantage, or are single people the ones that have better chances?
