If you are good at poker and know systems etc. (I know nada about poker), you can make a pretty good profit. I know one who won $1500 one night with a $65 stake.
Of course, if it was that easy, everyone would do it. You can be the world's greatest poker player and not catch any cards, just like you can catch great hands and lose your entire stake to someone who has just a little bit better hand. As an example, a buddy of mine won $600 in an online tournament and promptly brought it to a high-stakes room, where he lost his entire bankroll. He had a full house - and lost to four of a kind.
Add to this the complexities of cashing out, especially if you're under 21. It's a pain in the ass, even if you are of age. Multiply the difficulty if you're under the legal gambling age in your hometown.
Don't get me wrong- I love to play, and love to have a little extra spending money when I win the tournaments we play at the dorm or if I win a few bucks online. However, my point is that poker, and the cards you get, are much too random to justify it as a "job." At least for me.
If you want to get into poker, check this link out... there are a number of places that will give you some bonus cash just for signing up with them and putting up with the ridiculous amount of spam that they like to mail out.
Note that not every place gives out free cash, and not every place offers poker... However, Royal Vegas (http://www.royalvegaspoker.com
) and Seven Sultans both give free money and offer poker.
MNeo- try something like Internet Marketing (Quixtar, etc). Not a bad deal if you're looking for a more stable Internet job.
Good luck in your quest for employment. Online poker questions? Post 'em here... I'll try to answer them.
Create your own luck.
