    I'm a beginner programmer and I've been learning python actually for about 3 weeks now, but I am interested in learning about Java too. Gotta say compared to a simple
    print("Hello World") in python, the way to print hello world in java seemed way more complicated. this video helped me to have a better understanding of how python scripts work.

    To be honest, in my 3 years of experience, I hadn't come across a very straightforward and understandable explanation of Static vs Non-Static. Whenever people try to explain it, they tend to prioritize either time or quality, sacrificing one over the other. But in this case, you managed to provide a nice explanation without compromising on either time or quality. Great job! ( I was really struggling to explain this to a friend)

Finances have been tough and the faster I can learn, the faster I can get my life back on track as an automation engineer and you just made sense of 2 months of scrambling trying to fins out how to use this language. Hell, until this video, I was still confused on what exactly a class is, and you just flat made sense of it for me. Definitely going to check out your courses, you are the MAN!

You definitely made some of it make sense…like I get the feel of what is actually going on now. Versus looking at a bunch of codes just doing what I can to follow along. I was like why I am even writing this, why does it have to go here, what is one line doing for the other, etc.. I was feeling like I needed an “Intro to Introduction to Java” class 🤣.

      Yeah I looked it up and the limit under normal circumstances is 2,000. Conservatively assuming each one puts out one 10-minute video a week, that's 20,000 minutes of video a week.
      There are only 10,080 actual minutes in a week. So if he never sleeps, and watches them all at 2x speed, maybe he could pull it off.
