Jakob Greenfeld:

I recently discovered a simple step-by-step process that significantly increased my personal productivity and made me happier along the way.

It costs $0 and no, it’s not some note-taking or to-do list system.

The steps are:

2. pattern-match to identify your mind’s most common modes.
3. learn to pick activities that match each mode.

But that probably won’t hit home until you read through his explanation of each step.
