Where have you found the biggest difference to be between making $10,000 a month and $100,000 a month?
$10,000/month is achievable through sheer tenacity, consistency, and caveman-style intellect. $100,000/month, at least for a service business, is not achievable that way — you actually have to learn how to do business: hiring, building productized systems that run without you, etc. (You can hit $100K/month as an affiliate or in e-commerce too, but that path needs more inputs like startup capital and inventory.) I focus on service businesses specifically because they have the lowest barrier to entry and made the biggest impact on my own life, but scaling one past $10K/month by brute force alone doesn't work — you have to actually learn to run a business.
