A common mistake to think they want or are interested in doing something else/better.
Many enjoy what they are doing, they weren't gifted in the studies area, or were given perfect bodies or weren't gifted with patience to run 9 to 5 jobs and slowly piling money up.
Some absolutely love sex, and are good at it and want to be paid for it and being treated well with gifts some people get them.
Remember if this kind of ladies didn't exist, you wouldn't be here using these services, and if you use these services it's because you need them.
I didn't always have this outlook but with time it changed.
