"Composition is definitely what I'm born to do, and it came last"

David Friedman's quote speaks to the concept that composition is his real calling in life. He believes that it is something he was born to do, which it has pertained to him last. This might suggest that he has spent a lot of effort and time searching for his real purpose in life, which composition is the outcome of that journey. It could likewise mean that he has actually been working on other things before he understood that structure was his true passion. Either way, the quote talks to the idea that structure is something that he was meant to do, and that it has actually concerned him at the right time. It is a tip that in some cases it requires time to discover our real function in life, but that it deserves the effort when we do.
