Never run a business as a worker making ends meet. You're one recession away from failure. If you are not putting back a healthy margin to build a business, save for the unknown and opportunities, you're in a bad place that will likely bite you in the long run.
Do whatever it takes to put off hiring people as long as possible, and then push way way past that. Never hire people unless forced to take loads of money in exchange. Your efficiency will drop drastically and they'll be worth a tenth of yourself for half of your money.
