This is my main problem, especially with online betting.
I get a line up and always seem to stick it on something right away even if its a sport I have little knowledge or care for.
Last week I stuck my winning on Chicago Bulls at home to some team and started watching it at about 0230, they were up 10 points so I turned off and went to sleep safe in the knowledge it was money in the bank. I woke up and they had lost in overtime.
I would love to be a pro gambler but will never have the discipline or knowledge for it.
