I think part of the problem is that source code is always in flux. So to think of the satisfaction of completing a project seems difficult to imagine.
Big corporations invent new “features” and then axe them, even if the products are delightful; venture capitalists obsessed with building to exit on profit alone; open source developers trying to make a name for themselves by building something in Rust to improve performance by 5%.
Compare that to something like architecture or woodworking, gardening, baking, painting—creating real tangible things.
My recommendation is combine the two: use arduinos and/or raspberry PI to automate water delivery in your garden. Stuff like that that you can experience the value at first-hand. :)
