I agree with the fact that it all depends on the decisions that I made. If I got beat by a 3 outer or 1 outer, usually, I just chalk it up to the percentage of the game that exists as luck. In my long run, I feel like I've hit 4% outs about as much as they've hit me. If I lost due to being out played or just being an idiot (isolated incidents when semi-committed late in MTT's, for example with solid
equity value and no hit with tons of missed outs on river, which I may win with
bluff shove 50% or so of the time) then I have to take a break and remind myself that I didn't lose because I'm addicted to
gambling, I lost because I falsely interpreted the info/numbers that I had, and I do tend to make the right decisions way more than I screw up. That being said, I don't typically splash my chips without the nuts, and the 80%/20% ratio of skill/luck usually ends up, for me, 78.5% making the right decisions, 1.5% failing to make the right decisions, 10% good luck and 10% bad luck, within a couple percent margin of error. My "bad decisions" late in, say, a $.50 MTT on the bubble, would be like calling a 4 bet cold shove preflop with QQ after I put 40% of my stack as a 3 bet. (Terrible move, I'd say, usually, but marginally unsubstantial loss.) I'd still give myself a little time to examine what I did wrong and why I made the call, determine that, if it was, in fact, the wrong call, I can't blame luck and once again, remind myself that I'm not an addict. (Whenever I lose a decent amount [$5 or more] I feel like I'm addicted to gambling and should probably cash out now, or seek help or something... But you're not addicted if you're winning!)
