A group of students asked their lecturer how to let go of their anger. The lecturer asked them to take a big bag and pick some stones at the river side. Each stone will represent something you despise... After a few days, a student came to the lecturer and claimed that his bag was very heavy, and the lecturer asked him to put down the bag, and he feels released instantly.
Anything that irk you is like a stone to you, if you kept them in your heart is like putting all the stones onto your body. Let go all your anger and things that annoying you, you will be released and happier.
