I don't think Jack Roush spends 12-18 hours a day building his engines.

If you get my drift!

You might try the same.

Unless you're a perfectionist. Then you're screwed.

To Jack, there is an acceptable return ratio. As we have all seen!

It might be time for you to "manage" the business rather than "work" the business. You have succeeded in building a good reputation. Now, train others to do the work under your supervision. Learn to "work smart" rather than "work hard".
