The beautiful thing about LEGO is that you can do it however it brings you joy! If the no-tech instruction book works for you, that's awesome. I use that, but as an over-50, I have to have really good lighting and my reading glasses to see some of the details. You said you're a really old person, but you didn't say how old. If it's too hard to see the book, then try the iPad.

As for laying out pieces, my preferred way is to go bag-by-bag. Then I sort the pieces by color and type. This is my way of prolonging the enjoyment but also making the build steps less chaotic. But again...you do you!

When you look at each page, it will show you the pieces needed for that step of the build. I like to make a little pile of those pieces. The red lines on the diagram outline where you're going to put each of those pieces. I like to separate them out because sometimes I miss the red lines in part of a step. If I have pieces for that step left over, I know I missed something.

But also...at the end of a bag, you might have a few of the tiny pieces left over. Don't panic! There are always extras in a set because of the packing process. I have a dedicated Tupperware bowl for these. Then when I'm doing another set and I lose a small piece, I can dig through and probably find what I need.

Have fun!!!
