When I build I don't just sweat, I bleed, and  if I reacted to pain and/or failure by crying rather than laughing, tears would likely be a daily occurrence, too. A true Warrior, not an armchair spectator, enters the fray prepared to fail, bleed, and possibly die. Doing so because it needs done, without concern for their personal survival.

Building one off prototypes by oneself like this is hard. But coordinating the capital and the people to do so at scale is exponentially more difficult. This applies to the contractual, digital, and virtual realms, as well as the physical.
