Yes, I totally agree that the best investment of my time would be to talk with customers.

But maybe I am doing the process wrong. I read a lot about how to start by choosing a group and discovering their ideas.

Currently I have some kind of Idea Journal (actually a .md file in a cloud) where I write ideas, needs, problems, possibilities. It might not be the best way to do this.

I was looking for an easy way (from sitting on my desk) to filter them. Initially I get enthusiastic about all of them remembering the context where I wrote them and I think I am a type of person optimistic so I catch myself finding a lot of reasons why most of them are good.

So I read some books about startups, ideas, lean, ... and I got some questions to ask myself about them. This made the filtering process better.

The reason I asked this question was that I wanted to know also more practical examples of what do you - HN - do before taking the first actions (first investments of your time) in the project you want to build.
