I've played 100NL since 2007,  up until this year I'd never lost money over 2 consecutive months, a losing month would be a pretty rare thing.

This year I've played fulltime and switched to 6max, my game has improved a lot from previous years. I have put a lot of effort in to my improving my game. I've spent 10hours a week stoving, running CREV sims, watching videos and have spent my bonuses and rakeback on coaching, software, and training sites yet have faced results so bad I no longer consider myself a winning player.

What I'm asking here is for opinions on whether this could feasibly be variance? If it isn't, whether it's worth continuing as I fear my game simply isn't improving at the pace the games in general are.
