I think that's a noble goal and you've asked a difficult question. It's not easy to get involved in the lifestyle and something as awesome and all-encompassing as what SM can truly be can seem at times that it's worth basing your whole life around.

But it's not.

There needs to be something more in your life, a reason for living, something to strive towards and give you purpose. No matter how good it could ever get, trying to fit BDSM into that hole will only give you heartache and constant disappointment. You're looking for something big and BDSM looks big, but it will only leave you empty wanting more. Which is not to say that it's not worth anything--it can tremendously enrich your life. But it has to enrich your life, not be your life.
