@ Happiness's house
Imagine that happiness is a house which consists of three rooms. Divide the things that make you happy into three things for example: travel- to meet your lovers- reading. When you are in the saddest times of your life, knock at the doors of the three rooms. If you cannot enter the room of travel, enter the room of meeting lovers. If you cannot also enter the second room, enter the last room of your house of happiness. Certainly, you will find a room that you can enter of the three rooms in the time that you want. If you imagine that your happiness is in this house and if you refuge to this house in the time of your unhappiness, you will be fine as soon as possible.
