Why didn't they teach us this in school?

When I started teaching I was ecstatic to begin to "invest/save". My plan was to retire with ZERO financial worries. Thirty years later, after prudently contributing to my 403b, I now understand why it has not lived up to my expectations despite some outstanding market returns. I am on a mission to share my story and why my new strategy both aligns with my values and beliefs, and, has CRUSHED the earnings in my 403b in a fraction of the time!
