Enjoying every bit of this, both on the audio and the business sides. So, so true about the huge list of things you're responsible for that most folks have no idea of. I have three friends who've made reasonable successes of their own businesses, and they work like dogs. That's a minimum, and being smart and lucky helps too. If you're the type who's most happy when working at something, and your significant others tend to say things to you like "Can't you just sit down and relax for a couple of minutes?", you might be a candidate to go into business for yourself. But most folks who want to be their own bosses probably shouldn't.
I don't know whether this was an actual figure or some BS anecdote, but I seem to remember a statistic about 4 out of 5 business startups cratering in the first 5 years.
It's best to look at it as a disease or an addiction. I've started 6 businesses. 2 of them have been successful.
I'll probably start another business or two in the future. Because I think it's fun. Yes, it's hard work, and yes, it's something you can't forget about for an instant, but it's also the best fun in the world to me. Creating something from nothing is a wonderful feeling.
I actually get irritated when people say, "You have to slow down," or "You have to take a rest," or "You never have any fun, you have to get out, see things, do things, you're missing out...blah blah..." No. I don't. I love what I'm doing, and I'll keep doing it as much as I want, thank you. You're not the arbiter of how I enjoy my life, unless it impinges on your own. And I'd much rather work on a new prototype than, say, sit back and catch up on the latest episodes of whatever TV people are watching these days.
One rule I'll keep for any future business, though: none of them will be financed by another business, none of them will start up with "comfortable" working capital...that's a recipe for failure. Start with your own money, be hungry, be scared. That's the best motivator. Playing with other people's money (from VCs, banks, family, wherever) encourages a "screw it, ain't mine," attitude that is absolutely poisonous. If you segment the numbers for business failures between businesses started with YM (your money) or OPM (other people's money), I bet the results will be very different between the two.
