I made about £50 in a day, working double hours at work. Haven't made anything of the internet yet...
I won a prize in an online poker tournament worth about $11,000 in one day. Also won about $1,000 cash one night, but of course lost a big amount of that over the long term. I don't play poker anymore because it's too mentally draining and frustrating because to make a living you have to always think of the long term and take the losses without getting emotional.
I once made about $14,000 in a day, trading forex by spreadbetting (really exceptional for me, a combination of good planning, alertness and extremely good luck).
A few hundred from the days I have off, and decide to do a little article writing . Not a whole lot compared to you other guys, especially those who are good in blackjack. It's steady, though. Which is nice.
I made over $1,000 twice doing nothing out of the ordinary to get it (just my websites converting especially well). I sold websites and such for more than that, but I wont count those because it took me more than 1 day to get that ready..
