What Would You Do?

What if we could go back in time-let's say-15 years ago and talk to ourselves at that particular time in our lives. What would we say? Would we discuss all the awesome experiences, the heartache, the elation, the disappointments, the opportunities? Would we offer counsel in anticipation of what to come? What would our younger selves think of the lives we opted to live and where we decided to go? Would the meeting itself irrevocably change the course of history? There are so many possibilities in these kinds of meetings and although they do not appear to be physically possible given our understanding of time, what if that understanding is wrong and we can receive future messages or send one back in time? Oh the possibilities!
