Simply put ... Spot a particular pro poker player style of play that appeals to you most ... read his literature and imitate his style. You can also add some personal touches to it to make it your own. Been seeing good results since I started using this exercise.
The more I learn about poker, the more insight I get about the relation between luck and skill involved in the game. As my friend Ari put it, luck is definetely involved in the game but the skill part is to put yourself in situations where luck has a minimum say on the outcome of your battle.
