There’s a certain amount of luck and serendipity in anything we do, but it’s seldom the key factor. I hear it most as a dismissal of the success of writers and other creatives. Sure, Famous Actor is good, but it takes a lot of luck to make it big!
You know what else it takes? Talent, perseverance, educating yourself on how to navigate a career path, not being an asshole when you meet influential people, and usually many years of hard work. A blogger who’s been writing every day, networking, and participating, and then writes a NYT best seller isn’t just lucky.
