How did you build your bankroll?

I'm looking for suggestions on how to build a bankroll to play 6 deck 25 dollar tables. From what I've read, I'd need about 10 grand. I'm considering doing the kamikazee thing with 5 or six hundred and starting on betting 100 a hand and just gambling until i get my roll. Any suggestions? Thanks.

Obviously you know that you are considering a high risk strategy. Your mindset is that of a gambler, not an advantage player. Nothing wrong with that as long as you realize how high risk it is. You bet $100 on the first hand, split double and lose. Repeat on the second hand and there goes your bankroll.
A more reasoned approach is to play at a $10 table ($5 is even better but I can understand why you wouldn't want to start that low and only certain venues even have $5 tables). Build up your bankroll slowly (although you can still easily lose your bankroll)and graduate to $15 tables. You should add to your bankroll with as much as yoyu can afford from each paycheck, assuming you have a paycheck. Even a $10,000 bankroll at a $25 table is not a guaranteed win.
As an advntage player, you are the tortoise, although you seem to have the hare mentality.
Godd luck.

I realize that that is extremely high risk and really dumb, but, then again, dumb people win all the time. My logic was that I could build a big bankroll quickly gambling, rathering having the ride it out at a 5 dollar table. I probably will try to build slow though. Thanks.

I built mine by playing heads-up 2D with short sessions, and wonging 6D. It's hard to get a decent EV at a RoR less than 10 percent without wonging and being selective. But I tend to be Risk averse, and it sounds like you're willing to accept more risk.
