Think about how much it costs to learn more. Sometimes you want to build confidence by knocking off the easy things.

I've always found that working through ideas in written form really changes the thinking.

Make sure that you take the time to think about how other companies might respond to your idea, both those companies already in the market you plan to target as well as others that might imagine targeting that market.

I find social media as fun and engaging as the next person, but imagine if all the creative talent that was pouring into finding increasingly clever ways for us to broadcast daily banality (and then serve ads based on what is learned) instead focused on some of the UN Millennium goals? The world would be a better place.

Now, I worry a bit about the TEDification of the world where style trumps substance, so hopefully you have a good blend of both!

I've never seen impeccable logic be sufficient to win both the heart and the mind.

Most companies are built to execute today's business model, not discover tomorrow's.
