I had that realization today, that I was getting frustrated too easily when I had to learn something new and difficult in iOS, and inevitably I'd bring up Chrome to load HN & co.

This morning I followed the workflow in the OP, and it really improved my performance. I set a timer for an hour, really put work into understanding everything, and when I was done I took a 35 minute break (it is a Sunday). It was rewarding and productive; I'm going to keep this behavior up. Thanks Jiri

I know it sounds silly, and I joked about it for a while before trying it. I put HN, reddit, and news.google.com in my hosts file pointing to localhost. The extra few seconds it would take me to modify that file, and the knowledge that I was breaking something I explicitly put up for my own good, keeps me from visiting these sites.

On the other hand, I've learned a lot of new distracting sites this way :(
