Years ago, when I was a first year medical student, I was at the airport & a man approached me asking for help accessing the airport WiFi. During a quick conversation I found out he was a Cardiologist, & we’ve been in touch ever since.
I’ve always gone to him for career guidance whenever I needed it and he’s never hesitated to pick a call or return my emails.
We’ve only met the one time, but I hope to meet him again someday. He’s making real changes in the world out there and I hope someday, I will too.
