Have you thought about physical habits as well as mental? Have you tried to ingrain any behavioural habits in order to benefit your life?
For example, some (perhaps odd) personal examples include trying to improve my tongue posture and body posture. For habits in general, do you have an opinion on how much time should be allocated for focused and 'unfocused' work?
PS I really enjoyed the post, I have been trying to many of the same things, however I haven't been tracking/tallying occurrences which I will try! I like the idea that given our neuroplasticity, we could potentially engineer mental and physical habits for long-term happiness!
