It can be SO difficult to find the time to practice self-care, and I feel like it needs to be done routinely for it to have the right effect.
11 years ago (maybe even to the month), I took up running. I had just weaned my daughter after the previous 14+ months pumping breast milk during my lunch and break times at work. Once I had sweet, sweet freedom from lactation, I realized that I could not sit at a desk for 7 hours a day AND sit during my lunch hour. So, I took up running. To this day, I run during my lunch break and eat lunch my at my desk afterward (and recognize fully that not everyone is able to have this luxury. I am eternally thankful that I do).
Running is the one thing I do for myself, by myself, consistently. It gives me a mental break, or time to get out some aggression or brighten my mood. It gives me time out in the fresh air, connecting with nature which I love so deeply. It releases dopamine, which my ADD-diagnosed self really needs help with. I feel really proud of this hobby and that my husband and kids see me doing this good, healthy thing. And, bringing it full circle, my now 12-year-old daughter has joined the cross-country team at her middle school and performs very well! I am so proud. :)
