# How many things are you trying to do at once?

> If the answer is more than 'one', we all know that works out. Use your Johnny.Decimal system to stay focused.

Here's a trick I've been trying. This is _difficult_, which I think reveals just how much we flit between tasks in the course of a day. I haven't managed to do it well yet.

Open a new note. Just a blank text file will do, it's not forever. Now, as you go through your day, every time you're doing _something_, identify what that thing is in your Johnny.Decimal system.

I'm at work all day. So whatever I'm doing has to be represented there _somewhere_. Am I working on a `21 product` or `31 marketing`? Helping `33 customers`? To make this easier as you start out it's good enough to note a category or even an area number. But an ID is better.

By the end of the day this note should be like a run-sheet of all the stuff you did. Every time you switch, update it.

Can you do it?
