If there was one business tool that I would say I absolutely "can not do business without" (My Diva Success System Planner not included) it would be my Mobile Office. I do not go ANYWHERE without my Mobile Office! It is either in my office or in my car, and I even take it in to all of my parties! If you need to get organized - and fast - set up a Mobile Office! You will wonder how you ever did business without it!
