This reminded me of when I did an internship in one of the banks here. Even as an intern staff, I worked my arse out. I'd leave my house early in the morning to come back late at night. It wasn't easy, but it was fun though.
PS:
hair growing in weird new places
You know our ancestors had hairs growing in weird places too. Maybe you're just de-evolving back to the ancient hominid species... I'm kidding :p
Yeah I reckon as long as you enjoy it there's no point even thinking about the amount of hours. I just think of the free time I had and how I just wasted those hours away regardless, so it's ok with me to work long.
And our ancestors had hair in the same places right? Just more of it =P
