I hear ya. I'm in the same boat right now. Thinking of a part time job to keep food on the table. I've only been in business for 2 years, but during that 2 years, I've been so busy it wasn't even a worry.
Just got to keep your chin up and focus on the important things in life, family and faith. Money is only a means to an end. It is nice to make it doing what you love though, right?
