Is There a Commitment to Small Tests?

If i want to accomplish a thing, how am i committing myself to it? A before we started recording, we were talking about the idea of small tests. And that's something that i've been trying to adopt a lot more in my life. When i have an idea of starting a new project, um or work with a new client, or anything like that, i ask myself, ok, what is a small test i can run to even see if this is a good thing that would be worth doing? You know what i mean? That way you're committing to it, but you're not overly committing to it and you can just run it and see.
