As Rob pointed out,i'm currently playing full time poker for a living. I'm 21 and my parents have given me a year to prove myself that i can make it work. My year is up in October and to date i have made $136,000. I keep a minimum of $10,000 in my account to allow for cold days. I always and i mean always stop playing if i'm down $2,000. On a good day i expect to clear over $1,000/$2,000 in cash games. However over 60% of my winnings have come from MTT wins especially the 100k win of $30,000 and 3 50k wins of $14,000 each and a 2 20k wins of $6,000 each.
I decided to quit university to concentrate full time on poker and although my parents were naturally disappointed they understood. I was studying biomechanics linked to my golf ( i play off +1) and i intented to go to the states on a scholarship but after breaking my wrist,i lost all confidence in my golf game and that reflected in my work at university. So here i am playing 7/8 hrs a day 6 days a week. It certainly limits your lifestyle but so does a full time 9-5 job, the hrs are crap for me as i'm 8 hrs ahead of EST so i'm like playing at 2 am through til midday.
My best advice is to not set daily targets because they simply cannot be made,you will encounter absolute shocking runs and bad beats. My worst week so far has been a loss of $8,000 where absolutely everything went wrong. It is stressful but the rewards to me balance that, i find no bigger rush than winning a huge pot or playing in a big tournie.
Any questions don't hesitate to ask.
