Simply being alive is the evidence that things work out.
Not perfectly. Not always in the way you planned. But the fact that you are here, reading this, having made it through everything that came before today, is a better track record than most people give themselves credit for.
Start noticing the small ones. The parking space. The person who held the door. The thing that worked out at the last possible moment.
Feel grateful for those. Then watch how many more of them appear.
