One good deed a day
Let's be helpful!
Helping another person every day not only increases the other person's well-being by making them happy, but also effectively increases your own well-being.
It doesn't have to be a big favor to do this. Very small favors, like holding the door open for someone, are also very effective if you are aware of them.
Did you perhaps already helped someone today without being aware of it at that moment?
