The easiest way to tell if your secrets are worth telling is to ask yourself if this is about hiding a truth or keeping your privacy. And hiding your ambitions or goals is the next most common “secret” people keep from their significant other. And you have a right to privacy, so if you want to keep a weight-loss, job promotion, or personal goal to yourself, you can. But you can also share that too. Sometimes, a bit of support from your partner can be helpful too.
