    While enjoying good incomes, physicians suffer from a lack of time. Between scheduled clinical work and being on call, it’s common to have only one full day off in seven. Not surprisingly, it’s far too easy to spend that entire day just trying to do the boring tasks for yourself and your family.

The good news, however, is that new research published in the Proceedings of the National Academy of Sciences suggests that many professionals can increase their happiness by using their incomes to buy back some of that lost time through the use of time-saving services such as housecleaners or online personal assistants.

Study authors Ashley Whillans and Elizabeth Dunn found that when people spend money on such services, happiness improves. Their findings suggest that “using money to buy time may provide benefits by serving as a buffer（缓冲器）against the harmful effects of time pressure on overall life satisfaction”.

Spending money on a big purchase, such as an expensive car, can feel good and serve as a reward for having worked so hard. Research has consistently shown, however, that the gains from such material purchases are short lived. Instead, buying back time and then using it to go after meaningful activities is more likely to result in long-term gains in well-being.

There are the obvious tasks that have been outsourced（外包）for decades，such as house cleaning or meal preparation. In my own physician coaching practice, it amazes me how many of my physician clients do not take full advantage of these classic opportunities to save time, particularly meal services. When your time is worth well over $100 to 200 an hour, how could you NOT pay another person far less than that to do the job better than you would do it yourself?

Regaining a couple of hours on your only day off can change your well-being. How different would you feel if you had a few more hours to spend quality time with other people, improve your health, or try a new hobby?
