We spoke about Live on Brighton Beach by Fatboy Slim.

Band name: Healthy Advice for Living.

Band name: Threaten to Fall.

I mentioned about Mindform which is a sort of self-improvement community I participate in. It’s run by Ryan Bush who has written a few books including Designing the Mind: The Principles of Psychitecture.

I mentioned about my bullet journal. It is now an instrumental part of my whole day and I can barely imagine how I used to live without it. I got myself one of the official bullet journals too, it’s great; well made and full of thoughtful and practical features.

I mentioned about this SMBC comic: your ethical system is nuts, man!

You mentioned about Information is Beautiful.

You mentioned about Alain de Botton on The Diary of a CEO: The Love Expert: The REAL Reason We’re Lonely, Loveless, Depressed – Alain De Botton, School Of Life.
