I guess it's when we accept that who we are is a product of many factors that lie beyond our control. Sometimes it's okay to trade old dreams for new ones.
I have a theory: we forget.
It was never about what you could have had. It's always about what you can have. You can console yourself all you want, but before you know it, it's in the past. And those moments, they never existed, and that's okay.
It's okay to move on, to live fresh.
