Great to hear about your success story! However the number one ingredient must have been a good idea to start with. I hope to get the same viral success sometime for one of my projects, but its near impossible to foresee. Just work hard, keep afloat and hope for the best.
The usual warning against 'good idea' as most important ingredient, is apt here.
In fact, I read the story as a shout out to perseverence. More than 'an idea'. (Belief in) A good idea can help you persevere, sure. But execution is king. And for that, you need hard work, ability to push through, and perseverance.
