Let other people’s group plans fall apart without volunteering to fix them every time.

Someone has to make the booking, chase the replies, and work out who is driving, and when that someone is always you, it stops being a favor and becomes a post. Nobody assigns it out loud. It happens because you cannot stand the silence in the chat while a plan dies. The group learns fast, and then stops trying, because you always catch it.

Next time a plan starts coming apart, sit on your hands for an hour. Sometimes another person picks it up, and sometimes the evening just does not happen, which is survivable. You can still organize the things you genuinely care about.
