Most people simply can't wait six months for anything. Once you stick with something for five years, you get it; you're like, "Oh, I understand now. " Now, it's not just saying you had a business for five years, because, some of you guys, I'm looking at you, do six other things all the time.
You have the one business that makes you money, and you never paid all the attention you should be paying to it because you're always busy thinking about these other opportunity vehicles that could be better. When in reality, think about the logical extreme here: one guy starts a new business or new side hustle every six months; think about the other guy who does one business for 50 straight years and never does anything different. Who makes more money?
You already know.
