Be careful not to cheat yourself out of your end goal. If you get hurt who will make you money. If you retire, your business is worth less if it cannot continue without you. The best thing I learned in all my years of my business is it is way more valuable and easier to sell if it can run without you. It is okay to work and make that extra margin but don't count on it to survive. I purposely made less income the last few years as I put people in place to replace me. The big dealerships don't usaully put all their eggs in 1 basket and it can cost a bit more to structure like this but in the end it can be the safe move.
Honestly not a concern to me I only need to work like 1 day a week to pay the bills at the most and have a good safety cushion. I have zero intention to sell, having employees is way too much hassle. Few more years of it and will sell all the equipment and be set.
