I have a really bad habit of starting sessions off very poorly. I make a lot of stupid mistakes that I wouldn't usually make. I would usually only come out with a profit if I play for a good few hours. If I do start to play well after my mistakes, I'm spending ages making up for them. And it can knock my confidence and I'm more likely to make even more bad decisions.
Basically I wish I was more consistent at the start of sessions, and I was wondering if anyone has any advice or similair experiences?
