A new study examined over 21,000 Americans to find the right amount of free time to make life happier.

As free time increased, well-being also went up — to a point — and leveled off at about two hours and started to decrease after five.

And entire days free may leave us unhappy contrary to what we think.

When people find themselves with too much time due to leaving a job, retirement or a less challenging lifestyle and career, finding a new purpose in life helps put that found time to work in a positive way.

All of this may be why when you want to get something done, give it to a busy person to do.
