Think of how much more mature you are than your classmates. Even if you are of similar intelligence (and you are probably smarter anyway), most of them are turning in crap they made up after a weekend of drinking. You have almost a decade more of life experience, and if you're tired, it's because you've been caring for Oliver, not partying. I took a few undergrad classes in my early thirties after I'd already worked for a lot of years and had a year of grad school, and I could not believe how ridiculous the majority of my classmates were. It made me wish I could have gone to school somewhere with serious students, because even though I worked hard, there were a lot of unserious students around me when I was an undergrad and I would have really enjoyed going somewhere where that was less the case.
