When you receive a gift or money from someone, your brain releases Dopamine, the hormone that causes you to feel happiness and positive feelings.
However, when you GIVE someone a gift or money, your brain will do the same, but in addition, it will also release another hormone called Oxytocin, the hormone that gives you the feeling of falling in love!
Therefore, although receiving feels nice, giving feels TWICE as nice, so make it a habit to give more, because it's also the Sunnah!

A Thought: If someone, someday, give you a beautiful, expensive new necklace, wouldn’t you be grateful for the generous gift? But shouldn’t you be even more grateful for the One Who gave you the neck to display that on.
