I'm currently recovering from a stomach bug and woke up to a quiet house and time on my hands. I read a little bit, and then I started to think that if none of those words were sticking out by this point it was time to find something else. I went to thesaurus.com to go word hunting, as you do.
After some time, I found it:
1. The condition or quality of being serene; clearness and calmness; quietness;
2. Calmness of mind; evenness of temper; an undisturbed state; coolness.
[another definition I found and liked Here]
Yes. Exactly. I saw the word, and the definition, and it clicked. Pinterest gave me some pretty, inspiring pictures and there you have it. Serenity is staying calm through the chaos, of going inward and finding peace of mind there rather than through an outside source. Accepting myself and life for what it is, rather than living in an anxious state because I want to control all the things.
Happy New Year to you all, I hope 2016 brings you peace and happiness.
