Harvie: I always had a bad relationship with money, in the sense that I valued it too much.
Instead of moving up, I always cashed out for 'life stuff', when really it was an excuse because I was scared of losing it.
This was my experience for the first few years of recreational poker. Lots of cashouts but always grinding micros.
I think I stumbled on the quote at a good time for me, as Jan saw my have my first cash game losing month in almost a year. While the amount I lost in poker terms (6.5BI) is almost trivial in the poker world, IRL terms, I think, damn I coulda gone on a vacation with it. Instead a 3barrel semibluff with AKs seemed like a good idea.

I know that to continue to grow as a poker player I need to be comfortable with losses and/or extended losing streaks, so I try to view every setback as a growth opportunity. I just wish growth wasn't so darn expensive.
I think the next thing for me is to challenge myself to willingly spend X amount of dollars on sattys into a semi-major live event. WSOP has returned to Canada and my site is running sattys every week, so I know I should just say, "OK here's $300 just for that, and if you lose it, whatever," but man I hate saying goodbye to my children like that.
5 years ago I doubt I even dreamed of having this much money I'd be willing to lose at poker, but that's kinda the point of the quote. I actually DO want the money to change me in some ways, mostly around risk tolerance, also around spending money on things that will be +Happy or +Healthy.
