What's the minimal version of a service design library? So as you might know, it can be pretty complex. I do my service design principle library on a tool, which is quite complex, which is called Notion. It's a database with a lot of connection between other databases. So it's a professional tool. It's a very difficult thing, you might say, but I want to start today, Daniele, and I don't want to learn that crazy tool that you're using. I just want to get started today. Good news. You can do that today by just taking photos on your phone and having a special folder in your phone photo app, which is called Service Design Principles.

Just do that. That's already awesome. You do that, you're collecting experiences that you find inspiring, and you have them all in one place. That's already a lot. And now, because of that, you will have an observer eye to all the services that you build. But if you want to go a little bit further, but still keep it minimal, add a short text to every photo.

So maybe you can't do that in your photo app, because your photo app maybe doesn't have a notes feature. No problem. You could do that with having a different notes app where you put the photo in, cut a little title, which is like the tip that is suggested to you from this experience that you went through.

Or, if you feel a bit more in a sharing mood, you could say, Hey, I'm going to share. The photo that I took on LinkedIn, on Twitter, on anything else, on TikTok, and I'll share a little comment about that and why I find it inspiring. By doing that, you're not just helping yourself remember, but you're helping also other professionals learn from the experiences you are going through.
