Pro tip: employees cost money. This is something that you can't get away from no matter how you try. If you are an employee, be sure that whomever hired you doesn't want to pay you a lot. If they did, then we'd all go get jobs, and that is a preposterous notion. So, if you get the brainiac idea, like almost everyone else on the planet has had, to start a business and work for yourself there is one benefit that will happen immediately: You don't have to pay yourself. That's right, you can cut operating costs for labor to essentially a big zero if you don't greedily stuff your own pockets with frivolous "wages." This is a huge discovery in the world of getting rich slow, and we'll expound a bit in this post giving you a few ideas for the price of one.
The most common way to see this money-saving strategy put into play is small restaurants like cafes or teriyaki joints. How can someone make money selling food at an average of $5-6 per item? Well, if there's a bunch of paid employees you'd have to have an immense amount of bulk which we all know doesn't happen when you first start out. So, your best option is to just not have any employees and do all the work yourself. You can show up at about 4am to start getting things prepped, and once you get all your customers out the door by 10pm it'll only take about an hour to close up shop, leaving you a full 5 hours for transit, sleep, and free time. As an added benefit, you can eat while at work so you don't need to waste time doing that! You'll also save lots of money on your entertainment budget while working 7 days per week as you won't really have much of a social life outside of your new restaurant.
Any sort of start-up job you can think of will have these benefits though. Door-to-door sales for yourself, repair shop or handy-man work of some kind, whatever you're good at. Shoot, you don't even need to be all that good at something when you have this astounding business advantage. All the other companies will have labor expenses and yours will be free.
From the other side of the coin, I must issue a warning and there will be a full write-up on this later: if you get a job for one of these big companies, remember that they don't want to pay you. You are an expense. They'll call you an asset to make you feel good, but you can be sure they'd rather boil you in oil and serve you alongside a burger than give you a raise.
