The simplest productivity technique to understand, and implement, is "Get it done now"
It doesn't take any theory to understand. Just do it now. Whatever it is, just do it.
Aside from actually achieving something, this process closes our open loops.
Our brains are great at maintaining half finished thoughts for us. So as we work on an important task our brain kicks in and reminds us of that unimportant thing we haven't finished yet: those expenses we haven't claimed for yet, that email we haven't answered, that phone call we didn't return yet.
Here's a simple model of how our memory works. If we haven't locked in an action to a specific time, in a way that we know we won't lose it then our brain will iterate over the open loops and refresh the neuronal pathways keeping that thought alive.
We can clear the clutter. Keep our brain focused. Boost our productivity. When we close the open loops and just get it done now.
The fewer open loops we maintain, the more focused we will become.
