re: Poker & Starting my poker life - Opinions please
I always advise people to play with money that is completely disposable; i.e. that won't matter if they lose it all. Whether money from your 401k is disposable or not is up to you, but for me, it's absolutely not.
What I would suggest is to consider treating this as a shot taking type of situation. Put aside a few buyins, maybe 2-4, then take a shot at the game. If you find you're a winning player, your roll will grow, so basically NP. The main possible problem is that you'll have a large downswing before your roll is large enough to absorb it. Not great, but your net loss will only be the 2-4 buyins, and you can simply start over again.
If you're a losing player, you'll lose your 2-4 buyins, and the same thing will happen when you take your next shot. If this happens a few times, you can stop and look for ways to improve before returning to take another shot, and your 401k won't have been touched.
