If you are ending the year with anything less than a "Wow, what a year," then the change you really need to make this year is to enlist help and support to achieve your goals. Shared goals are more likely to happen.
Whatever the result, whatever happened, it is all your "fault" (read "responsibility"). By adopting this stance, you become empowered to take on any situation no matter what.
I'm not racing or chasing death, living under a perpetual doomsday clock; I'm making sure that I live every day as fully as I can.
