So what do you do for the living? What's your job? etc.

What are some of your favourite ways to answer this? I have my own business, but don't want to talk about it with some girls on tinder or first dates, also I'm not looking for gold diggers. Usually I say something 'kinda' funny, context related (our recent talk, place where we are etc), or shrug it off saying I have my own business/don't want to talk about job and why they want to "interrogate" me or sth. They usually stop pushing after that, but would like to have some go-to responses, so it won't bother me anymore.
