Mental health charity Mind has warned that people should not feel obliged to make new year resolutions because they can damage your mental health.
Many of the seven million people likely to make resolutions will set themselves up to fail by creating unrealistic targets, says Mind. Giving up is a blow to self-esteem and mental wellbeing.
People should set themselves simple goals instead, it says, such as being active, going green, trying something new or volunteering.
"New year's resolutions can sometimes focus on our problems or insecurities, such as being overweight, feeling unhappy in our jobs or feeling guilty about not devoting enough time to friends and family throughout the year," said Paul Farmer, chief executive of Mind.
"We chastise ourselves for our perceived shortcomings and set unrealistic goals to change our behaviour, so it's not surprising that when we fail to keep resolutions, we end up feeling worse than when we started. In 2009, instead of making a new year resolution, think positively about the year to come and what you can achieve."
