Any extra advices,comments or even threads i could look on to improve my aggression,postflop skills or even about 6max would be good.

I am thinking of playing 50-60k hands before moving up to 50NL.Which by then,i would be able to fix a lot of my leaks.Any probably 2-3 coaching session before moving up my limit.My aim would be around Mid March.

What do you guys think?
