Absolutely!! Go for the things you want to do now- you have a whole new life to live.
Personally, there are a lot of things I want to do and at closing in on 7mo, I have started some of them. I was very sick when I quit so I have had to pace myself. Two things I have done that I am proud of are starting to run again - I committed to three races over July/Aug/Sep and the third is this coming weekend; short distances compared to the marathon I once did, but amazing given where I was not that long ago....and I published my newest blog, since I am FINALLY inspired and creative and productive again. This one is absolutely a testament to where my life is and how I am seeking the best possible version of....everything.
We are fortunate to have these chances- I want to use up and give out all my talents!
