Whoever said that just about anyone could make 100k 4 tabling mid to high stakes limit games is off his rocker.
It takes a great player at either limit OR NL to be a consistent winner. Personally, Im an average limit player but very good NL player. There are many different reasons for that.
To answer your question, if you are making decisions with "no conscious thought behind them" its going to catch up with you probably sooner than later.
You may well be a natural poker genius though. I know Im not. Ive worked hard, studied hard and played ALOT to get where I am as a player today.
