Everything will flow

The dilemma is... When you care about someone or something, your emotion will be affected. If they can make you happy, they can make you equally unhappy. But you can't control that someone it something that you care about... So if you want to remain calm and peaceful, it seems you have to stop caring. You have to take everything easily. You have to give up both the joy and the sadness related to that someone or something. Essentially you have to be a monk... But I'm not. So now I tell myself, it's ok to be a bit more detached. It's ok to care while maintaining an independent and positive emotion. It's ok to feel angry or unhappy sometimes. Just bear in mind, everything will pass. With no exception.
