If you take on poker as a job your whole life will suffer, with no guaranteed results.
You will have to put in 12 hours a day, 7 days a week at playing and learning.
Your social life will be close to non existent.
If you take on poker as a serious hobby, it, like all hobbies, will create a platform on which you can build. You can learn how to keep pace with the game first off. I'm thinking 5 hours a day, 5 days a week might be to much, but that is not far from accurate (for me anyway).
As a hobby, there is no pressure on me showing much of a $$ gain. If I had a bigger steady income, I could even consider a net loss of $100 a month as 'entertainment'.
