Stickk which invites you to PUT A CONTRACT ON YOURSELF. I committed to losing three dress sizes by Christmas. I also put a monetary amount on this contract...if I do not make forward progress each week, Stickk will send the weekly amount to which I have committed to an ANTI- CHARITY. This motivates me immensely, because I would NEVER want to send my money to the group I selected. Since June, I have dropped one dress size...my facial features are more defined again, and my back and arms are stronger.
So, if you need an incentive to make a specific change in your life, you might want to take out a contract on yourself with Stickk!
