I love this quote by Harlan Ellison:
“The second secret, what they never tell you, is that yes, anyone can become a blogger. The trick is not to become a blogger, it is to stay a blogger. Day after day, year after year, post after post. And for that, you must keep working, even when it seems beyond you. In the words-to-live-by of Thomas Carlyle, ‘Produce! Produce! Were it but the pitifullest infinitesimal fraction of a Product, produce it in God’s name! ‘Tis the utmost thou has in thee: out with it, then. Up, up! Whatsoever thy hand findeth to do, do it with thy whole might. Work while it is called Today; for the Night cometh, wherein no man can work.'”
(I have adapted it by replacing “writer” replaced by “blogger” and “book” with “post”.)
