I will treat this as my business, not a job. I will not be an employee, so the more involved in the business I am, the better I will do financially. We will be more like a real estate team really.
As a single mom, I cannot wait tables all night since I have no one at home to watch my son. Right now, learning the business WHILE making some extra money with which to prepare myself for "the big leap" is a smart move (IMHO).
You also can look at being an assistant as a business. You are an independent contractor and set your own rules, rates, etc. There are plenty of VA's out there doing just that (virtual assistants) and doing quite well. Overall, I do not feel that is for me. I truly want to have a career/business in real estate. At least for me, starting out "assisting" was a great opportunity that I couldn't pass up.
Everyone is different and everyone has different goals. Mine is to have a balanced life of career and family. Ultimately, my son will always come first. I feel working for myself is the best way to ensure that.
