I'll go more into detail about this another day, but what I will say is that I'm fortunate to have had a "pre-adult industry" skill set - I can honestly say that it's helped me avoid a lot of depression that I would be experiencing otherwise.
My best advice would be while you're still working in porn - whether it be via being a porn actress, webcam model, stripper, etc - start developing your career (I suggest your own business) in your spare time.
I've found that much of the marketing efforts that I put into developing "Monica Foster" easily translate into the business I'm planning on launching and running. Often times you might even find that your adult industry persona may even ADD to your next business venture or phase of life. For example adult super star "Lupe Fuentes" just launched her own clothing line of which she also models for (click here to check it out).
If you stay positive and maintain a certain level of drive you can accomplish anything in life - no matter what you've done or where you've been. All that really matter at any point is where you are GOING!
