For me with running, it's just do something, maybe a mile at a slow pace, then start building the confidence and the habit again.
The hardest part is starting and not having an expectation of what you should be doing. Doing something is good enough.
I liked the older games more, OoT, TP, and SS. I wild love for them to do something more along the lines of skyrim, where the side quests have a good story rather than little things that don't affect the overall story or direction of the game.
