Hi everyone, this is my first post here after finding the site a few weeks back. I've played poker live for a couple of years and started my journey into online play with $50 on stars a few months ago. I've got up to $400 and am now grinding 10NL. I've been reading through the beginner's digest stuff but am feeling overwhelmed.

I understand the very basic stuff i.e. importance of position/aggression, pot odds, implied odds etc but i'm not sure how to best spend my study time to improve my game. What do you all feel are the most important core concepts to really grasp that will help me improve?
