Martin Seligman wrote the book Authentic Happiness.
Chapter 3 is entitled: Why bother to be happy?
Intuitively everybody on the planet wants to be happy.
However that is not enough for a scientist.
They aim to find empirical proof that being happy is beneficial.
And Seligman found some evidence that may be interesting here for us in the area of study skills.
He writes that happy people have a mental set that is expansive, tolerant and creative.
When happy one is more open to new ideas and new experiences.
And it holds true for young kids and adults as well.
When one is happy learning tasks are solved better, thinking and decision making is faster.
And in one study doctors arrived at the right diagnosis a lot faster when they were happy.
It iss always nice to increase happiness.
However now there is also scientific proof that happy students have better results.
As always: Just give it a go!
