Often, the most profound things are the simplest.
I read an interview with Christian Louboutin who said his father gave him the best advice of his career. His father was a carpenter and once told him that to make beautiful sculptures in wood you should work with the grain. If you go against the grain, you end up with splinters. Louboutin took this as a metaphor for getting along with people.
I think that is a golden nugget of advice, especially when people, skills and talent are the future of everything.
