Richard Hamming used to have "great thoughts time" - when he would only discuss "big" things, like:
- "where is the field going?"
- "what's going to happen in next 10 years?"
- I can't be thinking "great thoughts" all of the time, this is also probably related to "energy levels"

maybe great thoughts can be thought better when Thinking by Writing
- maybe connected to Great Thoughts that only can be thought with "hard work"?
