Everything we did was based around me - what made me behave the way I did in certain circumstances - were my assumtions correct,could other interpretations be placed upon things, was I projecting my views / behaviours on others or judging others because they didn't act how I either wanted them to or expected them to. It was extremely enlightening and I use these lessons EVERY day.
These are exactly the things that we all must learn to have the lives and relationships that we want. If you can't look at yourself critically, you stand a much better chance for a successful life. Success meaning our own definition of success for ourselves, not based on what we may want from others.
I also would like to add that things my counselors told me are the things that have remained with me. That and reading DB about 39 times made an impression.
