The article was awesome. I am following you fosho!
I do think though that we can find a middle ground that is positive but doesn't put "feels over reals (first time I heard this phrase and I love it now)."
For me, staying positive means not complaining if I am not going to do anything to change my situation. If I complain and do nothing, it means that I am being complacent and letting the world happen to me instead of using my agency to make whatever impact I can on the world.
I also used to be very oversensitive about people disagreeing with me (getting better at this but still working on it). I am positive by striving to not let my feels control the reals. I make sure that I am positive by not letting these irrational feelings make me act in a way that is passive. I also strive to make sure that a disagreement I have with someone doesn't interfere with my relationship with them.
Nice to hear you had a change of heart. This is one sounds much healthier.
