Swimming Pool

I wanted to add one more point. Eventually you reach a point when you exhaust the available literature. And whatever new information you find seems to fit into the existing framework you have created. And that part is pretty fun. :)

You remember when I first started out, I felt I was jumping into an ocean and the literature was an expanse so wide I couldn't fathom? The more I remained in this, the smaller the ocean appears. You start seeing people repeating similar arguments or raising similar issues. It starts getting the feel of "there's nothing new under the sun".

It feels more like a swimming pool now. :)
