At some point on your journey you'll realize that doing what you're doing is just as important as what it is you're building. Being alive and embracing the mystery of life. That's important to. It moves fast.
It's not always easy. But moving forward allows you to fill in the blanks. You start to be able to combine the unreleated concepts from before. 2018 was a lesson in combining what was already there. Already learned. Already there for assembly.
Even the hard stuff gets easier with practice and framing. You gain those attributes over the years, as an apprentice and then as an expert or teacher. As a teacher, one thing is known when other concepts about the bigger questions remain out of reach: You'll play this game forever and the more you play and practice, the better you'll get at it.
