I'd place mine firmly with the web ads ;)
I agree @ keep costs low, but I still think the definition of a lifestyle business is one that isn't growing in terms of the business.
If you liken it to a house rental. You could have the best house in the world, and be able to rent it out for $5m a year. That'd give you a great lifestyle, but even if you can manage to rent it out for $6m the next year, that's not business growth. business growth would be renting out 2 properties, 3, etc etc. Reinvesting the profit into the business in order to provide sustainable long term growth.
>> "I would think that's the nirvana description of any business, though."
So I'd disagree with this. Not every business wants profits over future growth.
