Echoing others, outdoor exercise is definitely the most restorative activity for me.
To add to this though, I also have taken up Photography as a way to add to or enhance my hobbies and activities.
I usually bring a camera with me on hikes, trips, walks, bike rides, nearly anytime I leave the house. It helps me see the world with my creative switch “on” but without the pressure of having to take an amazing photo - something I feel when I only bring out a camera for special occasions.
I also want to stress the importance of taking photos for yourself as the primary goal, and if only sharing photos that you personally like, not photos that you think others will like.
