I had a hunch for a product and, instead of building it, I put a cheap little test in front of real people first. The numbers came back honest, and they told me to stop before I wasted six months. I only pour myself into what is proven to matter now, and it has saved me more than once.
More people experience this than they realize.
You validate ideas cheaply before building, so you only invest in what is proven to matter.
If this sounds familiar, the Library can help you find the bigger picture.
