When I some says "sell X to Y", I hear "explain how X will solve Y's problem or otherwise make their lives easier". Because that's fundamentally what selling is.

I can talk for days about how marvellous the new iPhone is, the beautiful technology behind it, the marvellous processor and the high resolution screen that are, in their own way, feats of engineering that equal or surpass the Pyramids at Giza.

But that's not why people buy iPhones. They buy iPhones because having a portable device with internet that can make phone calls and take pictures and video and has GPS is actually really handy.

That's what "selling your work" is about.

"Hey guys, I made this open source operating system. If you're looking for an OS than enables you to completely control your machine, maybe you'll like it more than Windows." vs "Hey guys, I made this open source operating system. I wrote it in Rust because I like Rust."

> The only software that I like is one that I can easily understand and solves my problems.

selling is talking about your work with the end user in mind, rather than going on about the details of what you learned/how you did it.

That said, the latter approach is also interesting and useful, in that it helps others learn from your process.
