Roald Dahl wrote in "Uncle Oswald"

Embrace it with both arms, hug it, love it and above all become passionate about it. Lukewarm is no good. Hot is no good either. White hot and passionate is the only thing to be.”

And I think that's exactly what you and Bukowski are saying here.

Of course, the "don't try" line is an aphorism. Often enough, you won't know whether or not you'll like something until you've tried it. And sometimes, it might take a few tries and some warming up. That's only human. Often enough, though you already know deep down your gut "this isn't for me" while your mind hasn't caught up yet. Bukowski's poem might just be the bucket of icewater that some aspiring writers, stuck in a grueling grind over their keyboards, really need.
