knowing when to quit

[dico]

I would say on the whole I can win money at .50/1 and 1/2. However, no matter how much i win i always keep playing until i lose the lot. How can I make myself stop when up a certain amount:unsure For example this week I turned £150 into about £520 and then lost it all by playing just one more hand, then just one more etc Do i need to set limits? Do i need to do a challenge to motivate myself to stop:unsure Anybody else suffer from this? I guess it's just greed:$

Re: knowing when to quit I tend to put a time limit on how long I'm playing for and get out once its over. If I end up with an ammount at a very active table that I am uncomfortable with losing I move to another table. Say I buy in for $100 and get up to $300 but other players have similer stacks I move as I dont like the Idea of losing £200 on the turn of a card. Overall I have a bankroll of "x" and when ever I reach "y" I withdraw back to "x". If I get a decent win that shoots me to "z" I carry on playing back down to "x" or untill I have won enough to pay for christmas or something else that is desirable. The "x" bankroll is a million miles away from "A" so I should be O.K:ok Hope that makes sense:unsure
