A while back, I wrote a blog post and posted it to HN. Looked up the best time to post, labored over the wording in the title, everything. It got like three views and disappeared quickly into nirvana.
I was super discouraged and didn't feel like writing more about this topic (probably dumb after just one post but hey that's how I felt).
Then, a few days later, some random person re-posted my blog post to HN. This time it exploded and landed on the front page, giving me a couple hundred subscribers alone. Until now I have no idea why the difference was so huge.
This experience taught me that luck is just insanely important. Not sure how this conclusion helps though.
