A somewhat cheesy quote that helped me a lot is “you can be the juiciest, ripest peach in the world, but some people just don’t like peaches”. I used to try way too hard to be likeable and I agonised over people who didn’t like me.
There was an instance of a colleague being rude and unprofessional to me, and under the framework of “they don’t like me and that’s why they’re being unkind”, it put the onus on me to change, which wasn’t reasonable. It should be possible for people to not like each other in a working relationship while still being respectful and productive.
