Great read, highly recommended.
I especially liked this paragraph:
The absolute most important factor in getting a great deal in a sale is not having to sell. All of the work here happens well before the sale. Craft your business in a way that you would be perfectly happy to run it indefinitely. Get your work/life balance in order and your stress level under control. Go into a sale process with the idea that if you don’t get exactly the offer you want, you are 100% willing to just wait it out and run your business for another year.
