We may, rather sarcastically, respond to this question -- "Well, yeah, unless we want to build a business that would potentially save lives of millions of people, then grad school is probably a waste of time and money".... And our guest in this episode, Levana Sani, begged to differ and gave a full nod to the sentiment. She went to Harvard Business School, and then co-founded Nalagenetics -- a biotech company whose missions are to reduce adverse drug reactions and increase prescription efficacy by offering comprehensive genetic testing and robust information management systems to doctors and patients. In other words, she did it.   That being said, we concluded that it's not always necessarily the case. Going back to school can be a great path towards your entrepreneurship success, but it's certainly not the only path.
