But I think there's a significant difference: with music, as you play it, you are also experiencing ("consuming") it. And that's what also brings a lot of the pleasure to it.
With writing and videography, meanwhile, the act of production is usually a lot more decoupled from the experience of consumption. I happen to think that producing writing and producing video are also fun activities in their own right. But they don't fit into social life in the way that playing someone a song does.
I perform Bach terribly. But I consume Bach wonderfully when I play. I call it “Listening to the music with my hands.”

I have experienced this with many other physical activities. To ride a twisting descent engages your brain more deeply than to look at the same road or trail. To climb a boulder engages your brain more deeply than to look at the line.
Climbers pantomime the moves before climbing just as aerobatic pilots pantomime their routine before flying. Physical motion engages the brain a certain way that simply thinking, listening, or watching does not.
The pleasure of listening to music with your hands begins when you first make a single satisfying note happen. It is not necessary to be able to play what you would like to hear.
I'm not sure it's enough to keep me going by itself (honestly, I still like to think someone else may be able to enjoy it, eventually, even if this is probably unrealistic). But it's definitely a factor.
Normally enjoyment of the art making process for amateurs is just that, enjoyment of the process. If I want to enjoy literature, I’ll read the work of professional writers. If I want to enjoy the task of writing, I’ll write myself.
For most people, art making as a hobby is occasional, simply by the time & resource limits of regular jobs, family obligations, etc. While consuming art is much more accessible.
Some other things can be closer to a gray middle area. For me, that is cooking. I expect myself to be able to make really world class food even in my crappy apartment kitchen with limited time and a normal grocery budget. So when I can’t do that, due to time constraints generally, I won’t whip together something quick just ‘cause.. I’d rather simply transfer the grocery budget to restaurant budget and eat better made things.
Thankfully, since most of the very best food is found at cheap or medium end restaurants, and not too much at five star expensive places, this is fairly easy without changing my budget. But compromising to make a mediocre thing myself, either purely for the sake of cooking or to allegedly save money, is not interesting or useful to me.
I could imagine people feel that way about a lot of things.
The simple answer is that it completely ignores how the world works. Things don't decide to be world class. They are labeled world class after they have existed and were compared with other things that are not world class. If you decide to remove the non world class things from the ranking (because they were not worth doing) you will realize that the number of non world class things has increased.
You and only you decide if a thing is worth doing. If you want to learn Mandarin, so what? You will probably never be a best-selling or critically acclaimed author of Mandarin books. You are unlikely to be the next star in a Mandarin-singing boy-or girl-band. You will not be a TV host reading the news in Mandarin.
What of it? Does learning even a little Mandarin give you pleasure? Do it!
It’s insane to judge everything in your life by whether you are going to be in the top one tenth of one percentile. That is a recipe for constant stress an unhappiness, for forever judging yourself by impossible standards and coming up short.
