Hi Riksheim and welcome to our community!
It's a good idea to be honest and open about your game and recognize you need to change things to move on with it, so good start there.
What sort of changes do you think need to happen? Are you comfortable with your preflop game and need to study the postflop game more perhaps?
I kind of need a bit of both to be truthful, I keep forgetting things.
As for the up and down bankroll, well, I think we can all relate to that one! ♦
If you need any help to find something or want some information, just ask ok?
Meanwhile, you have a great time and I wish you lots of ups, not so many downs and we'll see you at nl25 very soon!
Regards,
Mal.
