Every Desire is a chose Unhappiness
In any situation in life, you always have three choices: you can change it, you can accept it, or you can leave it. If you want to change it, then it is a desire. It will cause you suffering until you successfully change it. So don’t pick too many of those. Pick one big desire in your life at any given time to give yourself purpose and motivation.
Especially the absence of desire for external things. The fewer desires I can have, the more I can accept the current state of things. The more present I am, the happier and more content I will be. Most people believe that constantly getting what you want will make you happy, without realizing these are fleeting pleasure, only to be replaced by fresh desires. They are on a hedonic threadmill with no end point, high costs (in terms of health, wealth, time) and depends on many factors out of your control.
