obviously, the patiance, what many comments mention, does not work for me, and I know 99.9% of players, probably everybody runs out of it sometimes. And you can't measure the loss, because of that in any meaning.
I have no best quality, or I can name many things for a while, when the 'while' ends, it is not anymore the best, so I can name something else.
Selecting the right level and structure tourneys, and play only those can be one day, when I will find 100+ in the 'perfect' category, nowadays, I struggle to find 30 within 4-6 hours starting time...
