And to add to that - I don't think when Google was launched, anybody thought about AdWords. This statement is technically true: > How do you make money? Be on the lookout for what I call “multistage rockets”: “Today, we’re doing X. But our grand plan is to do Y, which will be really profitable”. These usually fail. But, it is also completely non-informative. All startups usually fail. All (completely) new endeavors, even in established companies, usually fail. That does NOT mean though that it's not worth a try. You cannot generally anticipate apriori what will work and what not - and you CERTAINLY cannot anticipate it from the business plan (what was the business plan of Facebook? Instagram?). If you stand any chance to anticipate "what will work" - it's from the team, not the business plan.
