I don't have a secret, but I found what works for me and that makes it easier to upkeep.

I'm exactly the same as Miss E. As I go. If I'm in a room there's always something I can manage to do. My motto is 'do it now'. As much as I procrastinate whatever it is usually only takes 10minutes max. I do have a routine, but it's pretty quick.

Some people need to go hard for a few hours regularly, some need a list, some need a roster, some need a routine.
