Insecure leaders ridicule others. Secure leaders laugh at themselves. The ability to make fun of yourself opens the door to candor. It’s a mark of humility and a catalyst for learning. Great leaders take their work seriously, but they don't take themselves too seriously.

Gen GI Fellow Teaching: Do you know the different ways to know how many bands are left on the Boston Scientific Endoscopy banding kit? Fellows are often taught the second to last band is white, but did you know that if you lose track that you can count the knots on the bander at any time?

The love of reading is an endangered species. Just 16% of Americans do regular leisure reading—down from 28% in 2003. 41% of UK parents read daily to their toddlers—down from 64% in 2012. Books aren't only a source of flow. They're a gateway to empathy and lifelong learning.

The gut-brain axis is a bidirectional communication network between the gastrointestinal tract and the central nervous system. This dynamic system integrates neural, endocrine, immune, and metabolic signals, many of which are modulated by the gut microbiota. 🧠 1. Neural Pathway
