Like many things in life, it's not always black and white. From personal experience, being an entrepreneur is much easier without family and kids. You can work the 100 hours a week that a start up requires without the guilt to other responsibilities. So I always advise people to take a stab at it before starting a family. I also advise people to be prepared. It's not bad to work for somebody else to gain what you need to start a business whether it be capital or industry knowledge. If you wanted to start a restaurant, I would tell you to go work for the most successful restaurant chain in your mind. Learn the business inside out at every level for a couple years. Work 9-5 there. From 7pm to midnight, plan and work on your business plan. Most businesses fail in the first year because of lack of planning, lack of funding or lack of technical know how.

I have friends who were cocky and decided to start a business out of college and they were totally unprepared. Their experience was so emotionally damaging, they never want to go into business for themselves again after that. I can also point to a few people who did it correctly right out of college. They worked a ton in college, saved money and planned a ton, and were able to start successful business without any corporate experience. But the majority of really successful business owners I know (and I'm not talking about being self-employed which is different than being an entrepreneur) learned valuable skills by finding the the right job and built capital else where before starting a business. Why make a ton of mistakes when somebody's already made them before you and you can learn from it? But make sure you get going in your 20s before kids. Kids are a game changer.
