Yes, Bill Gates and Steve Jobs both betted on the personal computer. And those were the right decisions, and they knew it. But how many times have they created stupid, failed products? Microsoft Bob? The Apple Cube? These guys appear like they know everything they should always be working on, but they've gone through years of trial and error with various approaches. They have been around the block.
I would say both of these guys are so dedicated that they may not necessarily have the "right" idea, but they constantly tweak their ideas. Jobs successfully launched Pixar. Doesn't that make you wonder that having the types of traits that he does would make you successful in virtually anything you do in life? By the way, he has a very specific set of traits about him that allow him to see such consistent success. I recommend picking up "Inside Steve's Brain."
You don't know what's right. Zuckerberg launched failed businesses before Facebook. I know a lot of millionaire entrepreneurs who failed at 6 or 7 startups before they got it right. How does the saying go on the bicycle? You can't move forward if you're standing still, and you can't change directions until you're moving forward.
If I'm not getting at least 2 out of 4, then it's probably not worth doing. Learning might be the only exception.
That assumes that the "social and environmental impact" are going to be measured honestly and not just used as an excuse for control.
For example, even if you believe all of the AGW stuff, the "account for environmental costs" tax is around $2/ton of carbon. http://www.sciencedirect.com/science?_ob=ArticleURL&_udi...
That's a large pile of money, but it isn't going to have the "side effects" that the AGW people want. Those will require much higher taxes on "bad" things. So they'll have to either give up on the rant against said bad things or go with "sin carbon" taxes, which pretty much proves that they're not interested in carbon but sin.
you charge someone (an advertiser or customer) for attaching their name to or using your product/service and they agree???? we even have units to measure this, we call them dollars!!
