If you haven't much to show for this year yet, there is still enough time left in 2023 for it to be "the year that changed it all" for you. What is today you going to do for tomorrow you?
Things change. That's what they do. Being afraid of change is like being afraid of death. They are both inevitable, so you might as well get comfortable with them.
I want to be a builder of new things until the end. I enjoy the freedom and the security of the things we have built, but I don't want to spend all day "protecting my comfortable situation."
Everything is a choice, even if you deny that you are choosing. Everything is changing, even as you struggle in vain to keep it the same. So, acknowledge that you are choosing... and know that with each choice you step closer to that person. Every time you choose to do the hard thing, you are stepping towards being the person who isn't afraid of hard things.
