> While you practice the thing you want to learn, you will not feel good, especially not starting out. This honestly is a bit of an understatement, it really sucks and depending on the task, odds are you may want to lie down for a bit when you’re done with your first practice session. You’ll also almost certainly perform significantly worse toward the end of the session. All this is your brain and muscles getting tired. It’s a good meta-skill to learn to self-assess and pick up on this.
> Learning something completely new from scratch is really awful, and at this point most people are very disheartened and want to give up, which is unfortunate, because if they got back to it the next day, they’d find it’s actually gotten tangibly easier.
This certainly applies to some people, but not all people, and I suspect that the people who actually take the time to "learn new things" are those who enjoy the process. People tend to avoid things they don't enjoy, especially when those things are discretionary, so telling the people who don't enjoy the process of learning new things to do so anyway is preaching to the wrong audience.
