Think about validation like an iterative series of steps.

The first step (even before you have an idea preferably) is to identify who you want to serve. What target market are you going after?

I think it's wisest not to go after beginners. More about that here: https://justinjackson.ca/beginners

Next, you need to observe your target market. What do they struggle with, that they'd be willing to pay for? What evidence do you have of this?
