Writing down your New Year's resolutions, your motivation and your plan for action help solidify your commitment, experts say.
"Make sure it’s written down, not just in your head," said Dr. Marcelo Campos, a practicing physician and lecturer at Harvard Medical School. "Post it on your fridge or your wall to remind yourself about the commitment you made."
"With anything that we do in life, it’s a good idea to have things written down that we can track over time," he said, adding that goals should be specific and measurable.
Writing down your resolutions and action plan can also help you share it with others, which experts say is another key for long-term success.
