Notetaking

Whenever you're working on a project, whether starting from scratch or picking up from someone else, take notes!

You'll never know when you reproduce that same pesky issue. Having notes you can easily search through will help you troubleshoot much more quickly than searching on (StackOverflow)[stackoverflow.com].

Also, the simple process of reflecting on what you have done and writing it down, will help convert your short term memories into long term memories.
