Looking toward the future through the rose colored glasses of the past will lead to a lot of wrong because we forget what led up to that so called perfect past.

I do not remember the whole phrase of walk a mile in another mans shoes...(correct quote - You can’t understand someone until you’ve walked a mile in their shoes.”)...I have never really believed this, the only thing you really learn is there feet were bigger or smaller and your feet hurt after the mile. Now share a cup of coffee or a beer, then you can learn something about the person.
