There’s a trick to making all your dishes, cutlery etc. dishwasher-safe: you just treat everything as if it were dishwasher-safe, and discard the items which are not.
Eventually, everything you own will be dishwasher-safe.
How about applying this to friendships and relationships? You know you need certain things from people. For example to respect your boundaries.
How about not being afraid to set those boundaries, and communicating them? Many people will surprise you by actually respecting them. And others will show you that they don’t.
While I would not use the word “discard” in the same way with people (it just reminds one of narcissists) – you will recognize that these people are not compatible with what you need. And in fact, withdrawing from them will make room for people who will be “dishwasher-safe”. Who will fit into your life.
The same goes for hobbies, etc. – what works for you? There’s an abundance of people, relationships, things to do out there.
Don’t be afraid to let go of things which don’t work for you. Relationships are supposed to be fun, at least a little 🙂
