I suggested not to stress about New Year resolutions. It’s been well known that by the end of January for various reasons resolutions very often fall by the wayside.
Getting back on track is the key. By recalling the reason Why such activities did not work in the past can be the new learning. E.g., every January in the past if you invested in gym membership. Did you discontinue with attendance towards end of first month? If so, the reason Why may necessitate a review on the aspects of gym activities that did not entice or excite you.
