Now, less snarky and more serious, in any activity or discipline you choose, there are people who are dedicating their whole life to it, so you have 3 options.1) Hope your natural talent will compensate the less hours you dedicate to it (this is almost always false). 2) Accept you will never be as good as the crazies who spend all of their time on it.3)Join the fray and invest all your time on it.
Almost all great creations in humanity, things like Einstein's theory of relativity, Dante's Divine Comedy, Egypt's pyramids are the result of incredible and exclusive dedication for many many years.
For example, it's only been fairly recent since I dared to claim I'm pretty good at programming. And not even all aspects of it, but there are some aspects where I really notice I'm better at it than my co-workers. I've been doing this professionally for 20 years, so I guess it's about time I got good at it.
I've always thought I was pretty good at sailing; I think I have a talent for it. Used to do it a lot back in the day, but haven't been able to sail much in recent years. I'm not doing the upkeep, but I don't think I forgot any of it. I think I can jump in a boat and sail safely while teaching someone else. I don't think sailing costs nearly as much upkeep as something like physical fitness, which drops pretty quickly once you stop exercising.
I'm good at cycling, but doing the upkeep for this is easy: just take the bike when you go anywhere. I'm not as fast as when I was younger, but still faster than most.
I've been playing RPGs all my life, but I think I only recently got good at GMing (I've done it plenty of times before, but it was very hit and miss, and the misses sucked bad). But that's something I've been putting a lot of time and effort in lately. I clearly don't have any natural talent for it, but I've managed to accumulate quite a bit of experience over the decades. I still lack the discipline to do thorough prep, but experience fills in a lot of the details.
Despite having played a ton of different instruments (drums, keyboard, guitar), I've never gotten good at music. I lacked the discipline to practice every day, and though I would like to be better at it, I'm clearly not as passionate about it as I am about gaming.
For example, let’s say that you play piano, and you push yourself to a new level of skill and learn a few more advanced pieces. The decay rate for that skill is quite long, and with a very minimal level of work you can keep those pieces fresh for years or decades.
