Do you guys have stories of being productive with lack of sleep? Which point does lack of sleep hurt you instead of helping? Any stories if famous scientists or personal stores of juggling work and still making school a priority?

I’m determined to juggle my clinicals, work, and classes and just need a boost of motivation when I wake up after sleeping only 4 hours. I’m happy with my opportunities now but just want some stories of people “grinding” to keep me going strong
