Everyone wants to be happy.
Recently in Japan, a certain super-rich CEO was arrested for alleged breach of trust, even though he received several billion yen as his salary,
but he was still chasing more money, and money doesn't make him happy in the end.
The more you chase after happiness, the more you want happiness.
There is no end to this pursuit, and in the end happiness is only in satisfaction, not in other things.
So if you want to be happier, try to increase your happiness hormone - serotonin.
Serotonin is used as a medication to treat depression and is commonly associated with feeling good.
There are ways to increase this hormone without drugs, one of which is to take tryptophan.
The following study shows that after five hours on a tryptophan-free diet, a given rat had halved the concentration of serotonin (5-HT) in the brain.
So taking enough amount of tryptophan can increase your brain serotonin level which can lead to your contentment where happiness resides.
