It is a major hinderance.
I have very little regard for money when I play. I see money as points rather than actual capital.
My younger brother (18)takes this even further. He plays high stakes and I have seen him lose 4,000 on a hand to a 2 outer with one card to come. That would certainly cause me to take a break from poker for a few months but he just brushed it off.
Once you play a lot of hands you get used to getting lucky and unlucky. However, people like my brother and I have had a pretty easy life where money has never been a factor. Because of that, we are at a big advantage in poker.
The rich get richer, the poor get poorer. Unfair but true.
