Yeah, the difference is that "positive psychology" is scientific field, and they haven't discovered that "thinking positive" helps with being more successful. I changed the title of the sub-section.
I agree the titles sound obvious, but within each section we have lots of actionable advice (e.g. books to read about specific decision-making advice, the best tips we've found on how to save money, ideas for specific cities to move to), so I disagree these are not actionable for most people.
I think it's OK, I mean the heading's maybe a little similar but being "good" and being "successful" aren't really the same.
Good article, I think if one approaches it openly and without cynicism it's bringing together actually quite a lot of good suggestions. Have just ordered one of the recommended books - I must be in a receptive frame of mind :-)
I have some advice about how to succeed in life: "Figure out how to perform better in your life."
