@mattly The problem is looking for good advice.
But seriously, the vast, vast majority of advice in nearly all forms and locations come from an absolutist mindset. If you're just ideologically pure and disciplined enough about X, your problem gets solved!
People don't make much money saying things like "you may notice incremental improvement if you try these ideas. If they work, try a little more but don't overdo it." Ain't no money or clout in that kind of advice.
