What keeps me motivated...
Honestly what keeps me motivated is two things...
1. Wanting to lose the turkey I have hiding under my jacket
2. Saving all that money in car insurance, gas, taxes, repairs etc.
Its that plain and simple. Now that I have typed it out it doesn't seem like much as motivation but if you really put yourself into it and don't give yourself any other options (I got rid of my car so I didn't have an excuse) it really does the trick.
Hope that helps!!
