Yeah, but apparently, one doesn't need to make all those mistakes to learn because so many people before them have done them and learned the lesson, and they have advised others not to do them, so only if someone does enough research before they get started, they wouldn't need to go through them all. But, as we know it, newbies these days tend to learn only by experience, and they don't believe in "learning from the mistakes others made," even though that's a thing, and it's a very useful thing if we understand it.

Have you ever wondered why whenever you search about a problem you are facing in the internet, you find a solution to it? Or at least, someone else has asked the exact same question as you before you. That's because the problems that most people face already exist, and they don't need to experiment to find out the solution, they can simply search for the solution, and they will get it.
