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.

Could you then say to succeed you need a good idea and a good implementation of it, along with perserverance &c?
