Any sort of business publication or book will be the same way. That's just the nature of something as difficult or nearly impossible to quantify as business "success" - it's hard to tell what's luck, what's skill, what's skill disguised as luck, and what's luck disguised as skill. Best to take everything with a grain of salt, be on the lookout for those all too common fun "counterintuitive" findings (procrastination is good!) That make for good titles, etc.
