I completely agree. I come up with a lot of ideas and mention them to family/friends and 9 times out of ten the first thing they say about it is a huge obstacle or that it isn't feasible. I've always thought it was interesting that a majority of people, when presented a new idea, tend to go with the "Sounds like a good theory" reaction than imagining that it can be possible. That is why I admire Elon, in the face of all the critics that say it isn't possible he makes it possible.
