I don't think he'd argue that doing such things is always possible, all the time, but I think he might argue that we should try to move in those directions, even when our lives and feelings sometimes feel like something out of Dilbert or Houellebecq's Whatever.
#2 is a serious misunderstanding of flow and is against research arguing that flow states facilitate learning.
Flow is not easy-peasy non-frustration time, it is getting "fully immersed in a feeling of energized focus, full involvement, and enjoyment in the process of the activity." To deny yourself that is blocking yourself from the most productive and rewarding of human experiences.
One of the fundamental ideas of flow is that when the task is challenging enough to break one out of the state, additional skills are learned to return to the flow state.
In my opinion, to achieve your maximum potential as a programmer, you should be striving to hit a flow state as much as possible.

Thinking Fast and Slow
We as devs tend to seek optimal solutions as if they were a simple numeric quantity, where more/higher=better. We know this is not how things are, but the mental model is seductive in in its simplicity.
What I have learned over the years is that it is the constant change between different forms of attention and focus that drive me to be my best. Which means time, real time, away from what I do for work. And when I return to work after doing so, I appreciate it all the more.
You might be interested in Mihaly Csikszentmihalyi's book, Flow, if you have not yet read it. Although it has nothing to do with game playing per se, it helped clarify many aspects of my thinking when it came to why I felt I was 'wasting' time while gaming, and why I was wrong in that assessment.
It really has opened my eyes about how to deal with having a negative attitude and understanding the driving forces behind being in the "flow"
I have not read the book yet but it is on my reading list. I'm currently going through "Flow: The Psychology of Optimal Experience"  by the same author and it is illuminating to see the author examine a simple process such as enjoying a walk and reveal the intricate interplay of our consciousness, attention and self.
Perhaps you need to think a bit about your life theme, what you should concentrate in and how it unifies your ideas. This subject comes later in the book and my advice for you is to read the book from the beginning as it would give you lots of food for thought and might help to give you focus in your life as well as to your ideas (and what you worry about).
Regarding what do to with the multiple ideas, relax, you can't embrace the world. Focus on the ones that have a deeper meaning to you.
I think you have to be fully engaged in any activity you are making. If you want to relax, relax in a full paced way. Not worrying about the work you have to make.
If you must work, work in a fast-paced way, and make the job done.
The worst kind of works is the one multi-tasked. You dont get in a 'flow' state that is necessary for the most jobs people here in hacker news makes.
Two books are very good in the matter, The power of full engagement http://amzn.to/vdS1Tc and Flow http://amzn.to/t2bed6
