He also seems to have gone down an Epictetus/Stoic track after the initial interest in Epicureanism.
This is important to note, and to ask the question as to why this might have happened -- and could happen for anyone -- sort of a theoretical exploration as to why might someone study Epicureanism, but then later choose focus on Stoicism or modern stoicism.
Here are some reasons that come to me:
1) The given individual's lifestyle is not set up to be supportive or conducive to enjoyment in life, due to a busy or stressful schedule and/or a lack of friends to do enjoyable activities with.
2) The given individual's life situation is very unpleasant, making it difficult to relax and enjoy life -- a solitary lifestyle, difficult illness, mental illness, or poverty.
3) The given individual ideologically identifies more closely with "struggle" or self-advancement -- long hard hours of work to achieve recognition or fame -- in an attempt to improve one's financial well-being and/or to distract from # 1 and # 2 above.
Any other reasons not listed?
I myself feel that reason # 1 above applies to me -- though I will try to stick with Epicureanism for a little while longer.
