Well said. I think that before you can progress successfully past level 1 you have to be able to take good notes. (Even if using Poker Tracker) Pay attention to the table, especially if you are not in the hand. If you are new at this, pick one player (I suggest one to your immediate left or right) and just watch him/her, how they bet or check, what do they raise with, do they go to showdown, ect.
Then expand to others as you continue to play. Making a read is all about information and the more you have the better you will be.
P.S. Thanks for the post ChipFish
