No it hasn’t. Don’t equate “money I hypothetically could have made” with “money I lost”. That’s just self punishment based on flimsy speculation. It’s the same bullshit Netflix pulls when they say they “lose” money to piracy. It’s not a loss if the money was never yours, do not fall into that hole of emotional self abuse. Focus on what you can do NOW.

That’s their business model. Every business guru is just someone trying to sell a ghostwritten book. Stop listening to idiots online and start actually studying business development.
