Everyone should learn the basics of troubleshooting!
When trying to resolve a problem it’s really important to keep as many variables under control as possible so that you can find the root cause and fix it.
I see lots of people who try a bunch of things without isolating the issue first but can’t figure out what is wrong. Then because they messed with it so much it’s almost impossible to figure out.
This is important for car maintenance, home maintenance, electronics, computers. Just about everything that can break or stop working right in your life.
