Skills needed to move from small to high stakes LHE?

[mrjetguy]

I'm a 3/6 full ring limit player currently but was thinking today about my game and about what I need to work on. I got to wondering what the most important skills are that someone needs to develop before they can be a winning player at high stakes limit (30/60+ full ring online). Assume the small stakes player is already a winner at small stakes. I saw post a while back about what skills/concepts a person should have at each level of NL and I think it would be great to develop something like that for limit. It has to be on the minds of all aspiring low stakes players.

Anyone can respond of course, but if you aren't a high stakes limit player just try to let us know what you are playing right now.

Lets try to stay focused on full ring games if possible, even though I'm sure most things apply to shorthanded and full ring. Also, I know this has been sort of discussed before but I don't remember ever seeing a very detailed thread about this. Feel free to post links though.
