Health is a process. It's not a level we reach and then we are healthy indefinitely. Our body is in a constant state of renewal. There will always be things we could do differently, maybe better. The thing I always try to remind myself is to acknowledge what I feel in the moment and go from there.
Try not to resist the changes that come your way. Instead let life live through you. And do not worry that your life is turning upside down. How do you know that the side you are used to is better than the one to come? ~ Rumi
