Another thing to keep in mind, there is no such thing as a steady paycheck in order to plan bill paying. One month you may make twice what you do now, the next less than half. Unless your monthly bills are minimal or you are extremely disciplined you may have problems meeting your obligations on time. While the landlord or the phone company may allow you to be late now and again it won't stop them from also charging you fees.
When you work for one employer it's a rare thing to have your pay be late or incorrect and when it is they will correct it quickly. In mystery shopping you are just a vendor working with dozens and dozens of companies. If you are expecting $200 on the 15th you may not get it until the 20th If they paid you only $100 you may have to wait until the following month's pay cycle before it is corrected.
There are many, many things to take into consideration before even thinking about giving up your day job
Equal rights for others does not mean fewer rights for you. It's not pie.

Never try to teach a pig to sing. It's a waste of your time and it really annoys the pig.
