The short version is to set an alarm to call it quits at the end of each day and be DONE. No matter what! You did enough. You are enough! And, here's the whole story...
Depending on the circumstances, self care can mean so many different things. When my mom was going through heart surgery last summer, brushing my teeth felt like a day at the spa.
The absolute best self care advice to kick me off on this 15 year journey to become a self care specialist was from my mentor Dori West. I was just entering into my National Board Teaching Certification journey as a 3rd year teacher. The numbers were against me because only 10% of 3rd year teachers pass on the first try. National boards was more rigorous than getting my Master's Degree and on top of that I was teaching full time.
The advice Dori gave our cohort was that no matter what amount of work was finished or still needed to be finished for the day, at 8PM she poured a glass of wine and was done for the night.
