New Year's resolutions are for those who do not practice. If you are in practice for personal betterment and evolution, every day is the beginning and end of your practice in your consciousness.
Resolutions are for those who are drunk on substances and/or the delusion of personal immortality. Resolutions are for those who abuse or neglect their bodies and minds. When suddenly wakened by reality, their remorse sends them to altars and/or health clubs.
Practice can begin at any time of the day, month or year. Those who resolve to practice in a panic, seldom continue. Practice is difficult, but its rewards are inestimable, because practice has no end product to be tallied or weighed. It simply is as you are.
