I think it's a great thing to realize that you see other people through the lens of your own life. I believe we all do it.
Remember that the experiences you've had -- even the anger and pain right now -- are what will make you able to not only steer another course for yourself, but also have compassion with others.
We've all felt like idiots at one time or another. And I think I've exceeded my 15 minutes of stupidity many times over.
