Mr Nam, to be fair, seems to have spent much of his life pushing himself to the limit and dealing with the consequences. Born in Atlanta, Georgia, to Korean immigrant parents, he was aware from an early age, he says, that he needed to work harder than his peers. “My parents’ English wasn’t that great,” he says. “So, for me to not be left behind in school and social situations, it was on me to go out and make things happen and meet people and make sure that I was included and understood properly.” This led to a youth where, he says, he was “stupidly over-active everywhere”.

Music was a part of this. He played the cello and piano, was in the Atlanta Boy Choir and, in his teens, started uploading cover versions of songs to YouTube. He was also involved in social work. He volunteered at homeless shelters, tutored migrant children in English and made annual volunteering trips to Latin America. In high school, he was elected student body vice-president. At Boston College, he continued in student government, participated in its fundraising activities and launched a local branch of the Asian-American cultural not-for-profit Kollaboration. Talk about overachieving. “My friends thought I was insane,” he says. “There was a point in my sophomore year that I was so stressed I thought I was going to pass out.” Nonetheless, all the frenetic activity paid off. By the time he was in his senior year at Boston College, he had completed an internship at Deloitte and had landed a post-graduation job there as a strategy and operations consultant.

So, in 2011, life looked set for Mr Nam. But then he had second thoughts. “I looked back at my college career and I realised I had done so much and gone through it so quickly that I was uncomfortable with going straight into work,” he says. “I guess the biggest thing was that I didn’t have the opportunity to pursue my biggest passions, which were social work and music. Both were very much discouraged by my parents. With social work, it was like, ‘Well, go make money first, then go help the people.’ And then with music, it was like, ‘That’s not a realistic option. Don’t even think about it.’ So, I promised myself I would take off for a year and pursue one or the other, if not both.”

This resolution led him to India, where he joined another social enterprise organisation. This, he says, spun him out a little. He was haemorrhaging money in India, with no sign that his work was having any impact. “For the first time ever, I was depressed,” he says. “Up until this point it felt like, when I put my mind to something, it tended to work out in some way. But now I was thinking I shouldn’t be here.” He considered going back to Deloitte, but was torn. Perhaps this was an experience he was simply supposed to endure. Then he got a message on YouTube in response to one of his cover videos.
