Just one resolution

I am making just one resolution this year but I do think it will apply to just about every facet of my life.
Become more disciplined.
That's it. But really, what else do you need?
If you're disciplined, you will stay exercising and eating better, even when it seems neither are working. Eventually it will work - different people need different times. If you are disciplined, you won't buy everything in sight and leave yourself short. Instead, you will save and pay your bills off. You will do your job to the best of your ability and not whine when things don't go your way - after all, life is unfair and quite often, there's really nothing we can do about what others do - but we do have control over ourselves. So this year, I will keep exercising, eating more fruit, vegetables and green tea (which I actually prefer over black now), save more, shop less, help others more, practise and write more - because all of this will benefit me in the end.
And you gotta like that.
