A lot of it is doing what other people tell you to do. This may be encouraging or not, but I consider myself fairly versed in tech and there is still troubleshooting where it feels like trying things at random rather than any skilled insight to a solution. The take-away is it’s okay to skip an app that has terrible documentation and you can’t figure out. Start with something that has good tutorials and if that doesn’t work, try something else. If you can get that up and running those skills will carry over.
