Sure, but that's also the formula for staying small. Staying small is not necessarily a bad thing, especially since that's what I'm intentionally doing now. The OP's grand plan is to: I've decided that for the new year, I'd like to become less of a side gig tinkerer/random contract person and actually take a shot at making "real" money. On my planet, real money means more money than what one can do by themselves, which generally requires outside financing in some form. Crowdfunding is one way, but that wasn't available when I was initally making all my mistakes. The family decided that I was insane and wouldn't invest or loan. Friends offered plenty of free advice, but no money. I decided borrowing from the local Mafia subsidiary was a bad idea. That left borrowing from my bank. The bank loan enabled me to last long enough to sell the business.
Oddly, I also decided to stay small in the computer repair biz. The problem was that my first employee stole my customer list, formed a competing business, and tried to steal all my customers. It didn't work, but did cause me to reconsider some of my grand ideas.
Another problem was calculating how many employees I would need before I could spend 100% of my time managing instead of doing design or repair. My profits would then be based totally on their output, not mine. Note that I could not afford the salaries of competent employees and would probably be hiring a succession of permanent trainees. My guess was at least 5 employees, which was too many for my expected volume, leaving me to split my time between office and workbench, a situation I didn't want to repeat.
I'm currently 67.9 years old. Most of my friends are in roughly the same age bracket and situation. They previous owned a business with employees and are looking for something to do in retirement. However, instead of shutting down or selling the business, they're downsizing to the point where they're the sole owner, with no employees. The common complaint is that the business was supporting their employees, not themselves. I plan to do much the same thing, except I shed my empolyees in 1985.
