You see, a 'resolution' is great, but they often don't end-up working because they don't help you DO anything. You need a PLAN. A detailed step-by-step guide to whatever your goal is. That way you know if you're doing the plan or not, and if not you can adjust. It could be as simple as "I'm not eating bread and fast food for the next twelve weeks, and I'm going to walk 5km every day before work", or it can be far more complex.
Whatever it is, get a PLAN not a cool sounding catch-phrase. You're WAY more likely to actually achieve something.
