IMHO the key is removing empty media calories and replace them with load bearing subjects.

Might be naive of me not to understand what you meant, but could you elaborate on this?

Be upset when you're being simply entertained. If you see a commercial it's likely entertainment. Be upset when you see a commercial and do something else.

It's not an aesetic desire you're only tired of junk food for your brain. You're tired of being spoon fed predigested pablum. You're not happy with circular stories with characters that never change.

You're interested in yourself and being better. You're interested in your friends and loved ones and their journeys and lessons.

Stop watching TV or browsing the internet and, instead, make things (and read, and play).

How do I do this?

Step one might be "stop reading Hackernews so damn much".

I recommend Cal Newport's books, "Digital Minimalism" and "Deep Work"
