Do you think setting 7-9 goals is far too much?

Jordon Peterson's future authoring program asks you to set 7-9 goals - I don't remember the exact number.

I find that too difficult to manage.

I only have 3 goals:

I want to write a religious book. I want to write a psychology book. I want to get in better shape for both health and vanity reasons.
