I pump up the tires before *most* rides, but not all.
Depends on the ride, the bike, the time since.I last rode it, etc.
Lots of experience indicates that if I rode the bike yesterday and the tire still feels hard against my thumb, then it's within 5 psi of where I set it last. That difference doesn't always matter to me.
