Getting out of the rut

To say I've been in a rut is an understatement. I went so long without even a hint of excess, sticking to plan. Now it's been at least a month since I had a good day. I realize I need to change my perception but in the meantime, it's time to get back to work. I'm at the 190-188 range depending on the day, size 14. I want to be a size 12 by my birthday in a month, a size 8 by Alaska time in July. My rewards for getting closer to my goal weight and size is Beats ear buds at 170, a Kindle at 150, a dog at 125.
