Stop complaining!

I am reading a book called "Complaint Free World" by Will Bowen.  He advocates changing your life by training yourself to stop complaining and recreate your life "by design". By wearing a a purple silicone bracelet and switching it from one wrist to the other every time you complain, he says you can teach yourself to stop complaining.  After 21 days of not having to move the bracelet, you've got it!
I just ordered a purple bracelet which is free from their website : www.complaintfreeworld.org . Just pay 1.00 shipping and handling. No tricks.
In the meantime, I started three days ago by using a rubber band.  My family loves it because they tease me and tell me when I have to move it but that's okay. I feel better already. I find myself catching myself before I say something and finding a more positive way of expressing it or just shutting up entirely which is even better.
I want to be known as a cheerful person. You only have power over yourself in this world and I realize that I teach people who I am by what I say and do.  Thus, I intend to stop complaining, criticizing and gossiping altogether. Those behaviors do not jibe with a cheerful person. So I am not known in the way I want to represent myself.
What about you? Are you being treated in a way you don't like because of the way you act? Have you taught your friends and family to treat you like that? If so, I encourage you to try this simple technique to reverse the trend.  Be who you want to be. Be known in the way you really want to be known.
