How early should I be at Hobby?

Might be a bit of a silly question, but it's been a long while since I've flown.

Tuesday the 19th I've got a flight out of Hobby at 7:10 AM. Being somewhat earlier in the morning, I was thinking arriving at about 5:45 would be enough time to find parking and make my way through the airport.

Sound early enough, or should I plan on even earlier?
