If you want to succeed, you better start documenting your work and processes for everyone to see. I've been on teams where nobody bothered to do this, it led to a whole lot of confusion and mistakes. It's a shame that when things get busy, people tend to slack off on the documentation front, that's a huge mistake. Skipping out on documenting your work and processes will cost you big time, so make it a priority, or else you'll be sorry!
