I stopped playing fast games and I am trying to play a single or two 30 minute games per day. I am slowly increasing and I am almost at 800. I'll keep trying.
I'm still discouraged because I'm 38 and I've been playing chess all my life. I've read that a score of 800 is still a bad player. have I been a beginner for my whole life?
Of course you're not a good player and you still play at the starter level, but there many guys with the same rating who play way worse than you, you play more like 1000 which is solid. But yes, in terms of strength you always have been beginner level(which is complezly fine).
