This post is a little braggy but it's also one of the best things I've did and I'm genuinely proud of it. The result and the process wildly exceeded my expectation at the time when I started last summer and it made me happier, more efficient, and even gave me time to reflect (since there's not much else you can do while going on a long ride/run) mentally.
If anyone is thinking about it - give it a try! The starting months are the hardest, but once it gets going a positive feedback loop takes over. I've been able to convince some people in my life to start exercising when they saw me change so substantially in a single year.
