Time "Closet" Still Too Full

As I’m thinking about emptying my schedule or time “closet” it looks like it will still be too full when I put back all the things/activities that I love, that serve me and that are not outdated to have space enough even to put the new things I’d like to start doing, let alone give me space to just think or not fill up. Is this the point where I need to be constraining my priorities?
