You have the right attitude: having fun is all that matters. You're in a wonderful position where knocking 10+ seconds off your times isn't difficult to do. It may not be all that long before you realize a PB of under :30 is quite achievable.I have just recently restarted cubing.
My previous bout, a couple of years ago, lasted a couple of months, and saw me beat (once) the 60s barrier using LBL (typical average abt. 80s). I didn't have much success with CFOP though. Basically, I sucked at intuitive F2L
Now that I have restarted, I decided to use CFOP exclusively, and after some training I am starting to get faster in F2L, though I still average abt. 90s. Lousy, I know, but one week ago I was at 120s, so I am improving quickly.
The target, this time, is getting to an average of 40s and getting my PB below 30s. Will I make it? I think so. It will take some time though, but I'm having fun, so who cares?
