I've always loved Linux, even when it was kicking my ass. I can't imagine approaching it with the attitude "Ugh, I have to force myself to use this thing, and I know that it's going to frustrate me".

That sort of thing is a self-fulfilling prophecy, because everybody has cognitive biases. Since you expect it to be frustrating, you're going to remember all the times that it is and forget the times when it isn't.
