    New Year's resolutions(决心)have been around long enough that we all scent to stick to the same ones--hit the gym, lay off the candy, read more books, call your mother-regardless of whether we follow through with our intentions.

    While January 1st seems like the perfect time to have a new start again, exactly when people developed that mindset(思维模式)isn't common knowledge. It turns out that the modern belief of' a New Year's resolution isn't as old as you thought. According to many historians, the ancient Babylonians were the first group of people to make New Year's resolutions. However, instead of making a commitment to self improvement, they made a commitment to the gods to pay their debts and return any objects they had borrowed.

    An ancient Roman tradition from 46 B. C, bears even more likeness to modern resolutions. Emperor Julius Caesar declared January the month of Janus. Romans believed Janus looked backwards into the previous year and ahead into the future. In his honor, they made sacrifices to the god and promises of good behavior for the coining year.

    But the modern New Year's resolution didn't fully form until centuries later. The practice was common enough by the early 1800s. An article in 1802 states, "Statesmen have sworn to have no other objet in view than the good of their country. the physicians have determined to advise the use of medicine no more than is necessary, and to the very reasonable in their fees.”

    The first time “New Year's resolution" appeared as a phrase was in the January 1st issue of a Boston newspaper in 1813. “I believe there are a lot of people," the article goes, “with a serious determination of beginning the New Year with new resolutions and new behavior, and with the full belief that they shall accept punishment for all their former faults and wipe them away.

    So as you make (and possibly fail at) your New year's resolutions, know that you're in good company.
