But that's the thing -- most successful businesses (as opposed to youthful adventures that paint one as 'innovative' on a resume) are started by older founders who have a depth of experience in their field. As parent of a 3-yr old, babyhood goes fast. You'll be sleeping & able to put in extra hours, if you wish, at some point. You'll also notice that your patience for bullshit has decreased, your patience with actual important shit has increased, and by the time the kids in their teens you might be ready to be a founder who doesn't do the hustle-grind-performative-dance and actually... creates a business.
