When I turned 25, I was feeling rather old and wise, and I had planned to do a post on here to reflect on some of the things I've learned in my short adulthood while they're still fresh in my memory. I ultimately shelved the project for the time being, because I didn't want it to come across too preachy, and also because I felt like I still have a lot more learning to do that might make future me cringe when reading past me's writing.
I'm glad I shelved it, because I was right. There is still a lot more to learn.
