Happiness is in enjoying nature. Forget about infections, sun burns, flu etc.
Go and play with water, go for a long drive with your family, friends or boyfriend or girlfriend ahem ahem…. in winters stop using heaters and it would be so beautiful when there is chill outside and you are having a cup of coffee and doing shopping or enjoying the weather. Ice cream would also work. Just joking.
Happiness is in receiving surprises. That happiness cannot be explained and measure.
