Plot everything you do in the business by how much SKILL it needs from you versus how much FUN / INTEREST it gives you. Then free yourself from the bottom-left and work your way to the top-right — the tool Kevin's used to help clients more than double their productivity.
Step 1. Plot every task — emails, quoting, sales calls, locking up — into the grid by Skill (vertical) and Fun (horizontal).
Step 2. Everything in Low Skill / Low Fun — Delete it, Automate it, or Delegate it. Least fun for you, cheapest to hand off.
Step 3. Move diagonally up-and-right and repeat, until your effort sits in High Skill / High Fun — the work you love that pays you most. Only give that up when you want the business to run without you.
