I used to use color notes only. Mark everyone at the table green. EVERYTIME!!!
Once you make it to the money, mark everybody red, because they are at least as good as you.
Next time you see a red player at your table in early stages, watch his play and take additional notes. Later you will see that almost all players on the last three tables are already red :y:
If you come to the point that you make Final tables frequently, mark the players orange, or mark them orange already, when they make it frequently to the money, and the final table ones yellow. You may choose any other color, but succesful pokerplayers keep succcesful pokerplayers, and if you have a green one at the FT, you know he got there by luck or its his first time. Bet the hell out of him and see, how needy he is :secruity:
Up to Phil Hellmuth, poker knowledge is measured by success, and above all, a good pokerplayer always changes his style of playing during a Tournament
