There's been times in my life where I found it very hard to have motivation, so taking care of yourself can be a challenge - same with other areas like healthy eating and exercise. The thing that worked for me is kind of silly - I just discipline myself like a child...meaning I won't do anything pleasurable until I've taken care of myself first. I just force myself to do the task. Exercise also perks up the motivation. One thought that entered my mind was - what if I had an emergency...would I want to be taken to the hospital ungroomed lol.

I use this rule for cleaning the house too - I get the chores out of the way or imagine if someone was coming over. You're not the only one who struggles like this, but go jump in the shower now.
