Part of the craft of writing is having the audacity to subject your thoughts and opinions to public (and, as is often the case, anonymous) scrutiny. This is by no means an easy task. It's the pen-and-ink (anachronistic, sure, but okay because nostalgic) equivalent to stage fright. And to avoid this scrutiny, we employ all sorts of trickery. We're vague, but disguise it through humor, esoteric intimation, and sarcasm (a wit we're meant to grown out of, not into). We wiggle out of declarations with woulds, coulds, and shoulds. And sometimes, we even resort to... snark.
I recently re-discovered this poem by Taylor Mali. It's titled "Totally like whatever, you know?" and it's required viewing / reading / listening for, you know, like, everyone?
Have the audacity to make clear, concise statements. Play loud, and make big mistakes. Put yourself out there.
