I'm 41 now but when I was in my early 20's and thinking that being a comedy writer was something I'd like to do, I spoke to a sports producer who was in New Zealand covering the America's Cup, I asked him "How can I get this series (BTW I'd written a series) made?" and he said "Become a comedian".
About 15 years later I started doing Open Mic nights, it took me a while to take his advice but better late than never I guess.
Anyone else get any gold nuggets of advice they really wish they'd acted on sooner?
