DreamingDog, my next goal as I'm improving my overall energy and health is to go back to my exercise routine. I don't I'm ready yet, but I'd love to do a 5K. I'm more of a walker, but I've wanted to complete at least a 5k. I once started a couch to 5k training, but ended up mostly walking the event.
Funny you mentioning exercising... Just yesterday I was thinking if to calm my addictive personality I should find a healthy activity to get "high", like exercising, or working more hours, or crafting...
Yet best is moderation so I might just get busy with all the above without obsessing with anyone in particular.
