You know, unless you are making a ton of money then it doesn't seem like it would be a good idea to tell anyone that you do it for a living - too many idiots will say stupid **** to you.
But if you do make a LOT of money then you should be able to silence the idiots. Kinda like:
random person: what do you do for a living?
you: I'm a professional poker player!
random: can you actually make money from that?
you: *points to Lamborghini* Well, I made enough to pay for that!
Pointing to a 32" TV (in my case) just ain't the same. (I don't earn enough to make a living from it, I'd be less than $4K up).
