[2022] Any general advices?

I love this game so much, but I totally know that I’m still a complete beginner. (I’ll succeed all 3 objectives maybe 4 out of 10 times, when I play online with randoms…)

Anyway are there any general advices you could give to a noob? Imagine playing with me, what are some things you don’t want me to do, or what are some things you expect me to do in different situations?
