Sports/activities are great. I don't know how old you are, or if you have kids or not, but if you have little responsibility, I would pick an activity and then move somewhere that the activity is easily accessible.
If it's surfing, then move to somewhere and live on the beach. If it's skiing/snowboarding, live on a mountain during the season. Hiking, move to near mountains with fairly good weather (or bad weather if that's your thing), etc.
It's the advice I give everyone that feels like they are burning out since it helped me, but obviously everyone is different.
