The thing many dont realize is: If you have a good plan and follow it, you will very often have more freedom to try out new things than when your planning is chaotic or non-existent — because then literally every step is made out of fear, out of panic, to avoid pain or because other decisions froced you into something.
I say this because startups would argue about creativity and all that, but having worked aomw time both in art school and on film sets I can guarantee that the qell prepared always have more freedom than those who just try to figure things out as they go.
Thinking it is somehow more honorable to plan badly, throw peoples lifetime at the thing and getting a somewhat okayish result is really problematic in my eyes. Romantizing things that could have been solved by realistic (or even pessimistic) planning is not cool, it just shows me that you have no experience.
