Sury,

The two most important skills, I think, to long term quality poker results are:
1. Patience
2. Patience
3. Discipline
4. Consistency

Knowledge, experience, skill, agression, etc are all trumped by lack of patience (squared), consistency and discipline. Those are the bedrock to your game. That doesn't mean you play weak or whatever. Patience means you can't FORCE the issue. Discipline is knowing your game and applying it 100% of the time, plus knowing yourself, your limits, etc. Adn Consistency is just that. If you're inconsistent is applying your game, inconsistent with patience, etc. then there's no way to MEASURE your results over a reasonable period of time and ADJUST your game to improve. Game adjustments come in increments. You add a skill or apply a theory and then test it.

It sounds like you understand that you need to understand. And that's critical. All the people who don't care what they don't know and refuse to examine their own game (and mind) are doomed. Not potentially doomed. Just doomed. They are perpetual fish on perpetual tilt.

Good luck.
