Try to stay in contact with people who can be of use even if you don’t necessarily like them.

I have a friend who I despise. There’s nothing about her personality that’s likeable. She’s selfish, rude and arrogant.. BUT she’s extremely skilled at fixing/building things, has knowledge of programming, coding and a garage full of tools. Despite disliking her I maintain our connection just enough to use her as a resource.

I try to think of people as tools. I’m actively looking for friendships with people who have specific skills that can benefit me. Example: I have a friend who is a mechanical genius and can help me with anything related to my car.

I also kinda do something similar with authority figures/ people who can positively or negatively impact my wellbeing like at work. If I can tell someone is attracted to me I’ll be kind/flirty in order to receive special treatment/ consideration. (This doesn’t include sleeping with them but maintaining a playful attentive attitude towards them)
