Ok, so in my opinion you need to learn about the mos basic strategies to beat the microstakes to start with, then gradually add slightly more complicated theories as you start to win. I am inclined to say that self hand reviewing might not be overly useful until you become a winning player (though of course there will be arguments to the counter). My reason for saying this, is that I imagine you are in the sitting between the unconscious incompetence and conscious incompetence stages of learing, as illustrated below. For example do you understand about the different levels of poker thinking?
If you dont know what you are doing wrong, it would be very difficult to improve by reviewing your own hands. Of course asking opinions of others and reading strategy is very useful. However, you need to apply the correct strategies to the game you are playing.
My advice would be to watch the longer splitsuit videos on youtube. He breaks down and really simplifies the game of poker.
