Stop right now. You are using tutorials wrong, which is admittedly common. I will first explain how to use tutorials and i will then explain why and why you feel like the info will be obsolete.
Ok so how to use tutorials. There are two main usecases for tutorials:
When you need the absolute minimal intro to a tool.
Now it is important that you do not just watch the tutorial, because that gives you a false sense of accomplishment. You actually need to follow along.
You know how to do a thing, atleast mostly, but want to verify what your doing makes sense, find new tricks or follow the reasoning of somebody else.
Again the important part here is that you do it first then look at the tutorial. Youll get much much more out of the video or better yet text.
Anything else is atleast not good for you, its like consuming any other entertainment media.
So why not base your existence on tutorials? Well its not terribly useful to learn a hodgepodge of different shorcuts and interesting techniques their applicability is questionable at best.
What you instead want is to learn one boring surefire way to get you where you want to be 80-95% of the time. This knowledge does not have an expiration date because its not a trick that uses a obscure feature X it. It works as a foundation to getting you anywhere on any tool with minimal reteaching. You will also now start to be able to see alternate workflows and generate tricks daily.
Unfortunately youtube tutorials are often entertainment or repetition of much better done explanations.
