I'm all for New years resolutions, If they give you the momentum to be your best self, even for just a month then absolutely take advantage of that energy. And when that initial burst of motivation starts to fade, don't fall into a victim mindset just reset and make it a February resolution, then a March resolution , and so on 
The key is to embrace every opportunity for self improvement, If the New Year gives you that extra push, use it. Never loose an advantage that drives you forward . Wo!! LFG!
