I slammed the -80°C freezer shut and slowly walked out of the lab. It was midnight and I was exhausted. Another 18-hour day was behind me and all I could think about was going to bed so I could wake up and do it again.

And I felt a sense of nobility and pride over the fact that I made almost no money. But, after a while, I started thinking about where this lifestyle was taking me. Was I always going to be working slavish hours for the rest of my life? Was I going to be broke the rest of my life?
