They say money can't buy love, but it could buy happiness.

That's according to a new study published in the Proceedings of the National Academy of Sciences that claims spending money on time-saving services may result in greater life satisfaction.

A team of international researchers talked to 6,000 men and woman about their spending habits. They found those who spend money on services like cleaning or cooking, reported greater overall happiness compared to those who did not.

Level of income didn't matter, either.

In a second experiment, the researchers found that time-saving purchases brought more joy than even material goods.

They also said society feels obligated to complete all of these tasks themselves, and working a so called "second shift" at home, even when they can afford to hire someone.

The authors say we should all stop feeling obligated to complete our to-do lists, and stop feeling inadequate when we can't cross items off.
