I think the friend making signs is a bad example - he is actually doing something, having fun and making money. The reason he is not modifying his business plan is likely more complex than "building a tower of research"

However, the overall point of the article is still meaningful, it's something I find myself doing a lot - plan and think about a project but not actually getting started in any meaningful way. Obviously some amount of research and planning is necessary for everything, but doing that endlessly is the problem being described.
