This happened for me with lifting. I got so damn focused on a small part of the picture that I got frustrated and gave up. I just flat-out quit. Now... I'm back where I was in 2008 and realizing I made a big mistake by completely walking away from what I was doing and really kinda failed myself even worse than that initial failure. Trying to find my path again is proving to be an even bigger challenge than before. In some ways, it really haunts me.
So, right now.... I'm starting again in a very small way. Just walking and trying to rewrite some habits.... and finding "my way". Trying to rebuild a foundation that will carry through to the end of my days.
