In spite of a changing economy, Americans are determined to save and invest more money in 2010, that is according to an annual New Year's Resolution survey released by TD AMERITRADE.

While health-related resolutions, such as exercising more and losing weight, remained top resolutions, 75 percent of respondents report they will make at least one financial-related New Year's resolution in 2010.

"Perhaps we're seeing signs of the lessons learned from a struggling economy. Investor confidence took a hit during the recession, but rather than feeling discouraged, people are using this as motivation to get on track and be better prepared for the future," said Diane Young, director, retirement and goal planning, TD AMERITRADE.

The survey also revealed an increase in the number of women who plan to save more money this year - 66 percent, up from 60 percent last year. This compares to the 59 percent of male respondents who plan to save more money, which showed no change year over year.

Additionally, 52 percent of young Americans (ages 18-34) are more likely to make a New Year's resolution about personal finances in 2010 more than any other age group.
