When one person is doing it all, it can make for a heavy load. At the lake house, my friend Kim assigns everyone a night to make dinner. This is much easier than trying to assign everyone a task each night, or having the same person who always chooses to do the dishes hang out in the kitchen . This gives each person/ or couple to show off their culinary skills, share their favorite dish, and get involved.
In business, the same lesson applies. Delegating responsibility helps to relieve your burden and also gives each employee, partner, or vendor a chance to shine.
