Eliminate binary thinking! Things are generally not black or white, good or bad. We are all human, mostly trying hard to do life well.
Learning to observe yourself and note when you are being judgmental is a worthwhile effort and can be very enlightening. I am constantly catching myself when I see old ‘judgy’ reactions pop up. They can be very covert and many stem from our upbringing.
Without judging yourself too harshly, note when you see judgement of others come up and try to see them from a different light. There is always more than one story and looking at things with an open mind can bring about new lessons that make us more patient and empathetic to others plights.
