Another great essay by Frank Chimero: 

So, now I come to the part where I make my plea: no new tools, please. If you are interested in improving how people work, you should devise methods for work, manners of behavior, and methods of decision making. Document your ideology and apply it with existing tools, so nearly anyone can follow along. Why don’t you use our best tool? Language. Increasingly, I feel documentation beats an app if you’re trying to shepherd an idea along. This approach seems to have worked pretty well for David Allen’s Getting Things Done and Josh Clark’s Couch to 5K. Of course there are innumerable apps supporting each method, but the ideas are bigger than an app, so you don’t need to download anything. Buy a notebook or put on your running shoes. Commit to the plan.

Really enjoyed reading this essay. It is not about to-do lists, or project management methodologies. Being productive is about cultivating the right habits, the right reflexes to circumstances as they occur.
