Yes self awareness is important... and that is the primary tool.

Oi vey... Well when looking it up to try to explain it ... one of the explanations was OH MY... That will work..but it is like more of an OH MY GOODNESS or to me an embarrassment.

Recently I accused someone of being angry with me... (and I still contend that) but she said that actually I was angry (and I was...) but that I had projected my emotions on her.

I think that it would also be accurate to say... well that person does not like me... when actually I do not (at that time) like myself.

Those are a couple of examples...
