Can I live off of this money for the rest of my life?

I have been an escort since I was 19 and i am now 28.
I've never had sex with any of my clients.
I did this as a method to help pay for my college and it turned out to earn more then any career I could get into.
Some men I would go on dates with would give me a 5,000 a month allowance some 1,000 some even up to 8,000. Over the course of my time being an escort I had 3 serious men who gave me monthly allowances and the rest were one night hangouts sometimes they'd call for me to show up at another event after the first.
So down to the details I have around 730,000 in stocks my savings and checking combined. And then my home is worth around 460,000 I paid 380,000 for it and only mortgaged 120,000 which will be fully paid off in 4 years.
I drive a standard car an Audi A4 I bought it 1 years used for 28,000. I have a few nice purses that are a few thousand and several nice shoes but I've kept them all for years. Besides a few nice designer bags and shoes and some clothes I shop at Macy's and nordstroms marshalls.
So my questions is do you think I could live off of the money I have earned in the last 9 years or so?
If now how many years do you think it could last me?
If not do you have any suggestions of how I could stretch how many years I'll get out of the money?
Thank you
