You do have one, don't you?
If not, the smart thing to do is to start one TODAY!
Your to-list will be one of the MOST profitable tools you'll ever use and will help you become a person of mass production. If you don't begin using a to-do list, I can almost guarantee that the things you need to get done will NOT get done.
Remember that little voice in your head saying, "I don't have enough time."? If you continue to "listen" to that voice… well, guess what's going to show up? Not enough time.
A to-do list is a valuable tool to help you overcome some of the scarcity messages you may be hearing.
