Hey that's what they say, some shit about a pebble becoming a mountain... idlk, something inspirational like that!
Point is, you start out small, tiny even, then build it up, slowly, surely, step by step... I've been following this guy online for 4 years, this single project he's been working on. He created the characters himself (total of 20+), all while working for major industry studios (like DC and WB). Right now the guy has a book published, another book in the works, and a screenplay/movie for the first book produced by WB. A graphic novel they're turning into a movie kind of like Watchmen. I've never worked on something 4 years + straight.. but lately I've kind of realized that's the kind of effort it takes to become elite at something, to become an actual expert, that sort of dedication and commitment. Do something 4..5+ years in a row, you're going to be pretty damn good at it..
Just start small.. baby steps lead to monuments.
