Nah...your new guys are proly getting many hours of practice cause you are giving them steady work. Plus, you're managing the big picture, while they're just drones who are supposed to do the work fast. I, on the other hand, haven't had nearly as much practice because I'm both doing the work and finding the work, not to mention doing everything else. So I'm learning owning a business, running a window cleaning company, accounting, marketing, sales, etc. plus the technical skill of actually cleaning windows. If I was stagnant, maybe that'd be a problem. But not a day has gone by where I haven't learned and improved in some way since I began. Surely there's much more to learn, but right now I've created something from nothing, and it's working.
Besides...I don't need to be the fastest because I have no intention to be cleaning windows the rest of my life. I've always been a strategy guy so, while I'm happy to get faster and it means more money now, I'll be even happier if I get good at systemizing, hiring and managing. For me, window cleaning is on my "stop doing" list, but for now it's what I need to get started. So, I guess, ironically, you are right. This may not be the job for me, and I don't want it to be. What I do want, is for it to be the right business.
