Duracell bunny day

Some days I wake up in the morning and it seems a huge effort just to get out of bed. Doing the simplest of household chores feels like a titanic struggle and all I want to do is curl up under the duvet and sleep. Other days, I wake up feeling like the Duracell bunny on speed. The mammoth list of tasks on the to-do list is surprisingly achievable, the flat is amazingly clean and tidy and the mountain of work is reduced to a molehill in no time at all. Why can’t every day be a Duracell bunny day?
