This one is going to be short because I'm still very
green chartreuse in my developer life. My top takeaway from branching into software development and programming is to simply go for it. No one learns to code by reading about it. There are great tutorials out there, but writing your own is different.
Learning to code is learning a new language (more like several), and to be better is to jump in and fail. A lot.
Here's to failing, and succeeding, in 2016! 🎉
