Women are under real pressure to have kids, though. They have a biological clock. So women who are the typical age of entrepreneurs—25—need to be looking for someone to mate with. Think about it. If you want to have kids before you’re 35—when your biological clock explodes—then you need to start when you’re 30, allowing for one miscarriage, which is more probable than most young people think. If you need to start having kids when you’re 30, you probably need to meet the guy you’re going to marry by the time you’re 27, so you can date for a year, get married, and live together for a year before kids. If you need to meet that guy by 27, you are very distracted during your prime startup time.
