'You're the only person in the room that has a spotlight on them. How cool is that? C'mon that is totally cool, actually it's awesome! I've done it for over 30 yrs and I know how it feels!! The hardest part is to keep proving you deserve it'.
Want to get started in professional comedy writing!? No problem, be willing to start small. Simple as that. There's nothing wrong with having a TV or potentially multi-million$$$ motion picture script you're working on (as a matter of fact in a very true sense, I advise you always have a finished spec script) but in reality you should be willing to look around your personal market and find little niches and ins to help you begin writing for fun and profit!
When I was bitten by the comedy writing bug many decades ago I quickly became aware that part of the fun of writing comedy is to have SOMEBODY you're writing for.
