This is not true, unless you are putting more into your startup than your marriage. It's priorities. My marriage and child is always more important than money and chasing an idea.

Startups are very demanding on time and attention resources. Families with children would feel the strain of absent parents. It could work out in some cases but for the general case it’s not the best idea.

Um. Just don't do that? As with everything, this is a choice you make but nobody is holding a gun to your head forcing you to be absent in your family.

Just to put this into perspective, as the oldest child of 4 kids, and now a parent, I’ve constantly lived with competing priorities pretty much my whole life. I’ve always made time to be there when they need me. It’s surprising how understanding people are when you explain why you need to move a meeting (in case of emergencies), but usually, just blocking time in your calendar as “important meeting” does the trick. If you have someone managing your schedule, make sure they know that nothing goes there, ever.

If you have to travel, take a couple days before/after and bring your family; see the city. Even ask whomever you’re meeting where to go. More often than not, you’ll spend some time with them because people want to show off their city, which just makes it that much easier to sell when it comes time to do so.

Get your spouse onboard before you start?

Start a startup with your spouse.

This. It's great to have a hot secretary.

Okay seriously this can work but it will really force you to work on your communication skills. Which is probably a good thing anyway, for both the business and the relationship, but it's very challenging.

Not recommended. Did that and now we are having huge fights about serious stuff. Like Facebook ads and marketing copy -:)
