Making new resolutions can be life changing...possibly...at the same time resolutions can fuel procrastination. Sounds cliche but it is said if you 'fail to plan; you plan to fail'. Plans are good and some people like 'markers' for achievement. Like to wear the badge of achieving something within a set time.
I feel growth is fluid, yes make plans but possibly find a way to improve on those plans organically. I believe a lot more change is achieved with flexibility rather than rigidity. Never beat yourself up. Even failure has its lessons. Growth begins within and not with 'out'.
