Use this to turn your problem around. Try making a video for someone just like you. You already know what a good video looks like because you've watched a ton of them.
If your goal is to make a good tutorial video, you can take those play problems without any real world application and turn them into content. That way your problem becomes "teach xyz in 15 min on youtube" instead of "master xyz by myself".
Teaching others is often said to be the best way to learn something yourself.
As you publish and get feedback, you can lean on your viewers to figure out what to build next. Eventually you'll be an expert in your chosen domain and have a following of people and have great SEO if you want to start looking for work.
Note: I haven't done this myself, but I wish I had, and obviously youtube is filled with people who are doing this about every topic under the sun. This is my plan for when I'm done with "work".
