Maybe if you're planning on starting social activities in week 5 you could add in some research to the earlier weeks - it takes a while to find out what's available.
I recently added on to my regular social activity with joining a choir in January (we're doing a concert in May which will be fun), and am re-starting tap dancing classes this week (with my old teacher from childhood as she still runs the adult class even though she retired from the rest of it).
