Recently I started working on a project that required me to track my time. I didn't give it much thought until I started working, and that's when I discovered something-I have trouble staying on task. At least, I have trouble staying on one task.
If you're interested in personal productivity, you have more than likely at least heard of Getting Things Done (GTD)-the productivity system designed to move every task, idea, and project that's currently in your head (where they're prone to stressing you out and bubbling up when you're trying to focus) into an organized outside system.
"Work smarter, not harder." Chances are, you've heard this phrase before -- and probably more than once. The philosophy behind working "smart" is to maximize your productivity when you are working so that you can get more stuff done in shorter periods of time.
The best one for you depends entirely on your working style and personal preferences.
You can use a physical notebook around everywhere you go, but it's easier to use a to-do list app or tool that syncs across all your devices. That way, you can access your to-do items whenever and wherever you need to, whether you're at your desk, in a meeting, or on a business trip.
