The truth is, I'm kinda scared shitless. But worry never changed an outcome. And while fear is a main character in life (as is failure), it informed the plot much more when I was young and it made decisions for me.
Even when we have what we want, we still can't land in this moment. We cling to the illusion that there are indeed a set of circumstances that, once we achieve them, will finally, miraculously make this moment inhabitable.
Instead of panicking about a state you have not yet achieved, I urge you to live in the magic of the moment. Do not let thoughts about where you could have been, should have been, or need to be dominate your psyche.
