Half your favorite memories were days you thought were boring while they were happening.

Memory does not consult your judgement. The days that survive get chosen for who was there and how safe you felt, not for how interesting they looked at the time, which is why a long stretch of nothing much with your friends outlasts the big planned occasions. Boredom in good company stores unusually well. You are a poor judge of which afternoons are going to matter.

Given that, stop waiting for the days that look significant. Say yes to the aimless ones this week. The hanging around with nothing happening is quite likely the part you keep.
