$300 a day plan

[pokerb]

i have been playing 10/20 holdem online now for a little over 1 year now. here are some of my numbers over this past year:
-i average approx 25 hrs of play per month
-i average a win of approx 1,200 per month
-i make approx $45 per hour playing 10/20 (1 table usually)
-i win about 61% of my sessions, meaning i will win 6 out of every 10 times i sit down and play
now i have a plan to sit down with 300 bucks every time at a 10/20 table and if i win OR lose 300 bucks i get up and i'm done for the day. with this plan, if i can play everyday and if i can win 2/3rds (66%) of my sessions, i can make approx 3k every month.
does this plan sound possible? does anyone else here have a plan similiar to this? comments questions are appreciated...
