Regaining Focus

The older I get, the more I tend to reflect on errors past. I know it's really not good to dwell and I am the first one to tell people to move on already, but it really is hard. I think about all the plans I had for myself, the choices I should have made etc. But in the end, it doesn't really matter. Life is all about chances and circumstance. We are given more than one road and while the destination may be a certainty, the journey itself  is a little more arbitrary. We like to think we have control over things when we really don't. We have no idea what's in store for us but yet we still focus why ended up in one situation or another. Instead of focusing on why we got there, we should focus on how we got there. Now where to start????
