    8:37 pretty much how i made most of my money. just making things simple. take a non optimised solution, ask the client is what they actually wanted in the 1st place… get trimming. have cut out entire data warehouse systems for a handful of pre-made lookup key tables before.

    Excellent, but most of ur video animations do not show relevant examples of pictures or videos to show a certain law. Better redo the animation with relevant pics & vids, then ur video woyld become popular, after that I'd love to show it to my class.

    I started self-studying about designing so your video definitely made me learn some things. Subscribed immediately as I could already tell I would learn more from your other videos. Thank you for sharing with us (and to the one making the principles)!

    This video is pointless. You are just narrating what's already on that website. No value added. You should have said that upfront. Oh, you did. But you didn't. Dark pattern found. 😛
    This would be great video if you'd have given actual examples with screenshots. Great production quality though. 🙂

    these are great but without real world applications of these laws and real problem / solution examples, it's pretty pointless
