Sometimes life is too much. When it is, give yourself some grace and permission to take shortcuts.
There is a great book called How to Keep House While Drowning. It is such a powerful title. I have included some ideas from that book along with other resources.
Disposable Pre-Pasted Toothbrush
If brushing your teeth escapes you at times, leave these in places around the house, grab one when you are thinking about and brush away! The way it gets done is the right way to do it
Make up wipes
Sometimes even the idea of washing your face takes a lot. Try ones that are individually wrapped so they don't try out as fast.
These help when you are on the go and wondering "Did I put deodorant on this morning?"
