Sometimes it can be worth it to check to decide if it's worth trying to get back to sleep or if you may as well just go ahead and start your day a little early.

Waking up to an alarm can be unpleasant, but it's often necessary to guarantee being up when you need to, so I figure why bother trying to get back to sleep with like 15 to 30 minutes left unless I'm tired enough for the stress of only 15 to 30 minutes left to not keep me awake.
