Oh I'm definitely not a master... but I've been writing new AHK scripts every single day, multiple times a day... for years now... and I'm constantly looking for new ways to make them better and more efficient without sacrificing quality of work. The 10,000 rule honestly still applies... at least as far as I'm concerned... practice doesn't necessarily make perfect unless it is perfect practice, but it sure goes a long way toward building competency.
I still have tons of trouble with JS/JQuery and the like... for some reason ever since the cancer my brain is just very selective about what I can retain and what I can't... I'm terrible with JS even after years of trying to write basic scripts. I'll spend hours researching how to write a script... and finally manage to make a functionally primitive but workable script... then if I ever need to make the simplest changes to it, I have to research all over again. It's just gone. That doesn't mean I don't still write JS scripts... I definitely do... they just really suck and half the time after a week I couldn't even tell you how they work without refreshing my own memory.
