I have never had an LD when trying to - only ever had one when not actively trying to. I think it's a state of mind. You might not be trying to but all the things that need to be just are and you have one.

I play guitar and for a while tried to play every day. It made me better but I always found that when I didn't play for a while I always sounded and actually played better. It wasn't forced, it was natural.
