Don't give up. Instead, make another deposit and please do let me know which table you will be sitting at...
...on a serious note, it seems you do not have respect for the game of poker. To expect to become consistent after only one month of playing is like expecting to teach at Oxford University after spending a semester at community college.....
Now I am not offended at all because most people do not understand; they do not respect just what it takes for professional poker players to do what they do on a consistent basis. I wouldn't say you are "not cut out" for it either based on you losing two measely bankrolls of $20 each. I'd be more prone to say Gus Hanson is not cut out for it (a poker pro who is reportedly down over $18,000,000) than to say you are not.
But I am not sure you have given yourself a chance to know whether or not you are cut out for it. You clearly have an interest but how deep does that interest run? Are you lured in by the prospect of easy money? do you truly enjoy the game of poker? These are questions you should ask yourself.
As far as bankrolls are concerned I would say go ahead and deposit again BUT I wouldn't be depositing back to back. This is to say, once I lose a bankroll, I am not one to immediately deposit more funds and try again. to me, that would be just stupidity because what have i learned? I lost moneyt he first time so I need to be a little more prepared the next time I try again.
With that said maybe this kind of "schedule" would work for you:
DO NOT deposit funds again UNTIL you have read at least one book on Poker. A book I would very highly recommend is BILL CHEN'S "MATHEMATICS OF POKER." Now you should decide if you want to start out with cash games or tournaments. Books by Dan Harrington have been very informative in my opinion as well and they even come with workbooks where you are tested on knowledge you should have acquired from reading the book. Harrington has books on tournament play as well as cash games so you can pick and choose where you would like to start this poker journey.
So read a book and deposit again...if you lose that then read another book and deposit again......if you lose that then decide if you want to keep on going. Of course along the way it wouldn't hurt to also try to figure out what you are doing wrong and to try not to repeat those mistakes. I personally do not like to deposit funds too soon after having lost a bankroll; i feel there needs to be some kind of justification for me to re-deposit (i.e. i acquired new information, found some leaks in my game which I plan on actively plugging, and etc...)
I do wish you much luck.
