_____Resilience
Resilience is that very quality that keeps you going even when others stop believing, it is what makes an entrepreneur push and pull through irrespective of any kind of external pressure.
Let take a look at
Satoshi Nakamoto for example, when he released the Bitcoin whitepaper in
2008, am sure that most people may not have even understand what he was trying to achieve. Some may even have doubted Bitcoin's credibility due to Nakamoto's complete anonymity. Irrespective of that, he kept building, kept making improvements where necessary. If he had given up just just like others because of the world's initial doubt, we may not even have Bitcoin today, talk of less having this forum.
What kept our very own Nakamoto from
not quitting wasn’t just knowledge or passion, it was simply
resilienceSatoshi Nakamoto literally did quit his online presence and bitcoin development. So maybe it's not a best example of keeping on building, unless quitting was part of the plan all along.
But when it comes to attributes OP mentioned: For sure, they are something needed for any entrepreneur. However they are not just for entrepreneurs, but more like a generic list of qualities for being successful at life in general.
