There is a moment in every relationship when one of the parties senses its imminent demise. There's a moment of incredible clarity when your stomach drops with a heavy sense of dread, and you feel like control is slipping through your fingertips even as you try to hold on.

But what's regret anyway? Regret, I am learning these days, is a lot of things. But mostly, it's a slippery seed of longing, of looking back and asking yourself why you didn't know better when the answers were so obvious all along.

There is the before. And then there is the after. Happiness is what you choose, what you follow, not what follows you. These are the things I have seen, these are the things I now know, these are the things I will carry with me as I go.

I like to take inspiration from people who do things that I could never do.

Eventually kids become grown-ups too, and from there, the world is whatever they choose to make of it.

That you can look back fondly or even wistfully on pieces of your life and hound yourself with endless what-ifs, but nothing will change. The present will still be the present. The future will still unfold as it's meant to.

We all have those moments where we realize how easily our lives could be so different, for better or for worse. I met my husband at a gym in NYC! What if I'd joined a different gym? What if I hadn't worked out in the afternoons? These questions are endless.
