Internet annoyance: "Achievement Unlocked" "Become a master"

One of the things that annoys me when people talk about skills they are learning/working on is the concept of “achievement unlocked”. I don’t know if this is a relic of the internet age or it has always been this way, but to me doing a skill once does not mean you own it.
Skills, especially those in the realm of the physical arts can be very complicated and dependent on many factors. In order to own or unlock a skill, you need to be able to repeatedly do it independently of those factors.

One analogy I like is to compare this to marksmanship. Does hitting the bullseye once make someone a master marksman? Absolutely not. It’s about being able to reproduce that performance with tight tolerances of deviation under variable conditions that eventually make the master. Hitting a bullseye once can be luck; hitting it consistently probably takes years of focused effort.

I also think these days the word “master’ is used too lightly. Even worse when it is self-proclaimed.
You will not master anything in one weekend seminar or one online course, or even a teacher training immersion, or internship(regardless of how much you pay). In fact, you may not master anything ever in your lifetime, but don’t let that get you down.

The point I am trying to make is that people like to celebrate and announce their victory too early when there is still much work to be done.
Let’s take a basic handstand as an example. If we are using the standard of time, I think 10 seconds is a minimum for intentional balance and control, and somewhere in the realm closer to 30 seconds as a more pronounced display of that control.
Ok, so you hit that 10-30s freestanding handstand. Are you now a master of basic handstand and ready to move onto the next level? Maybe regurgitate somethings you heard to sell your handstand course and start teaching workshops?
Or maybe there’s more work to be done training at this level before you celebrate and announce your glory to the masses. Ask yourself these questions

Can you hit that hold every time you try it?
Do you need specific conditions to hit that hold?
If you had one try under pressure, would you hit it? If so, would it affect your performance?
The final question is basically, is your base performance of the skill repeatable to a small margin of error under varying conditions. If not, there’s still work to be done before you can say you own it.

I don’t mean this to be discouraging in any way; quite the opposite. I just want to add a dose of realism. You did something? Great! Do it again and continue the work.
That’s something I love about the physical arts is that learning a skill is not simple. It forces you to go on your own journey, during which you have a chance to understand yourself better. If you could learn any of this in one day, you could forget it just as fast, and it would no longer be interesting. Put in the work and keep putting in the work.
It will take years if not the rest of your life, and you may never master anything. Personally, I’m ok with that.
