You're already smart and can intuitively grasp the fundamental of what you're learning. The idea is from how much of a scam things sound when people sell you courses about skills you can learn fast but take a long amount of grind to get anywhere.
Everyone learns at their own pace. Even if you put deadlines, there's bound to be people that are not going to meet those deadlines due their unique circumstances.
And speed learning really depends on a person's interest in the subject, familiarity, available resources (including a mentor), feedbacks, innate cognitive abilities to process information, practical demonstrations, and testing what one learns while on the job.
Take for instance the claims of speed reading. You can probably make sense of the characters faster in your head as you read this post but the lag time to capture the wisdom of what the post is trying to say is real. And if there are no means to test knowledge acquired for feedback, how would you know you learned is enough?
I get the glamour of speed learning. Main character vibes, it gives people a confidence boost if they get the ropes on the job quickly, and etc. but learning faster doesn't necessarily mean getting better at what you learn. I say this from a quality assurance as I teach new interns rotating in psychiatry basic lessons they should've learned and retained in med school. They are quick to grasp the labels but couldn't even be bothered to recall the lesson once they see the real thing in front of them.
I know they finished the chapters quickly and do chatgpt to pass through the assignments. So now I should be expecting at least some proficiency from them, but the reality is much different. We can acquire knowledge faster than having the wisdom to use that knowledge.
So to anyone that parades how fast they learn things, that claim only has substance when they actually apply what they learned right and creating more knowledge from what they learned.
I learned from the textbooks first but now I created my own techniques to make my life easier on the job but this came from rereading the same sources and months of practice.
But I know there would be people that would fall for a 7 day or 30 day tutorial if they bought the digital product. There's a market for this and I guess I'm not the target audience.
Thanks for your time.
