A few thoughts: first read “buy back your time” by Dan Martell which is something you desperately need to do, and if you don’t have a great executive assistant that book will help a ton. Then read “Who not how” by Ben Hardy and Dan Sullivan. You need more “who’s” like an EA and Director of OPs or General Manager to take a bunch of work off your plate and those books will help. Traction book is helpful as well as the EOS system but those I’d put as slower but great steps.
This is a short presentation that perhaps might be insightful - it’s an into to his “buy back your time” book and it sounds you’re at the level with your business that he talks about pain and the thought of selling: https://m.youtube.com/watch?v=7PDn091o6_E
