Absolutely Agree with the message in the video!

I actually believe indeed that any successful company requires some luck. Without the luck, yu may be able to survive as a company, but will not be one of the market leaders. To become market leader, luck has to play a roll. But the opposite also happens, and maybe even more than having luck, companies with good products and services will not make it due to having the opposite of luck.

I would think (not knowing all the details), that companies like Microsoft, YouTube, Apple all had their shares of luck. Google for sure, I know that story a bit better; They were not their at all if it was up to the founders. They wanted to sell their PHD assignment to Yahoo and others. Then some angel investor heard their story by chance, gave them a couple of million and the advise to start a company themselves. More companies go bankrupt then survive. I believe this is 80/20 in SF/silicon valley.

Being critical, have financial planning as the most important element in the company, and never never overestimate (internally; externally you may have the paint to world more positive than it really is, but that is called 'Marketing' and 'Sales') + good execution of the plans are key for any success. And hopefully along the way, some luck come towards you and you are propelled into the next level with your business.
