Getting to the source of #3, another piece of advice is to never define yourself, or your ego, by the things you use.

You might program in C on Linux. You might game on an xbox. You might have tried Rust or Go and think they're pretty groovy. You might have an iphone.

None of these are a part of your ego. They aren't a part of your image. You don't need to feel attacked if someone criticizes, rightly or wrongly, your choices.
