Commitment Day is celebrated on the first day of the year to remind you to stay committed to making this New Year great. This is a time to commit to whatever it is that will make your life better for the rest of the year. Whether it’s work, school, relationships, or health related, nothing in your life can be successful if you don’t show complete dedication to it. Many people focus on fitness and health on this day, committing themselves to staying in shape. 5k runs are held in many cities around the United States to help get people dedicated to starting the new year out right.
