Perhaps this seems overly simplified but I find clarity helpful. If you’re hoping for a new you in the new year then new action is required. The way you look and feel right now is a result of your past and present behavior. In order to change yourself (physically or otherwise) you must change your current behavior. This doesn’t mean you must eat only veggies and run 5km daily. That is drastic and unnecessary unless you enjoy both of those things – though I wouldn’t recommend a diet made exclusively of veggies. Swapping out some processed foods for veggies and being active in some way on a daily basis is the beginning of a great plan and you can build upon this when you feel settled with these additions. I simply cannot state enough (even though I do so often) that small BUT consistent changes to your actions become new habits that change how you look and feel! New year, new you, new actions.
