I love the section about the first idea is probably not going to be the last idea. I've seen startups come in with a very set idea of how the product was going to work, only to find that the way it was going to work wasn't really what customers were looking for.
Rather than defining how a product should work, startups should define their mission and adapt their product to both accomplish their mission and meet the needs/demands of the customer.
I've been involved in a few startups and this is what I've learned:
1. Iteration is key and should be welcomed.
2. Validation, as noted, is incredibly important.
3. Continuing to validate iterations ultimately leads to a successful company.
Absolutely! Couldn't agree more with this. Most often thing I see is teams holding onto a solution to a problem that 1) no-one has, or 2) a few people have but no-one cares about. Sometimes they also over engineer the early iterations to a level of complexity that even prospective users won't "get it". Starting small, doing the research & interview legwork to define the problem, then design the smallest version of one possible product solution to it, iterate, review continuously...
