“It’s simple arithmetic: “Your income can grow only to the extent you do.”

And your growth is your responsibility.

No one will do it for you.

In addition to getting a coach, I have found creating your own growth assignments very helpful for growth.

My self-growth experiments are an example of this.

You can even try something bigger like finding a new way of doing something old like Tyler Cowen envisioned a new kind of university here.

What you want to do is only limited by your vision and creativity.

You can do growth experiments in the field of your work or in a totally different field to learn about it and cross-pollinate ideas.

What will your growth assignment be about?
