If you desire to become more productive, impactful, and fulfilled, you need to do two things (with an optional 3rd)
Understand what makes you productive, impactful, and fulfilled in the first place, and
Do more of that and less of the other stuff.
Optionally, get a coach. Someone to ask you the tough questions and challenge your thinking to get specific about what #1 above looks and feels like and how you can achieve it.
Someone to hold you accountable and inspire meaningful action from you for #2.
