I'd liken it to nutrition. Had this one seminar, in a room full of 'experts' talk about better choices for better health, yet, she admitted to a love for carbs or whatever it was on vacations with her husband and how even a moment of weakness would find herself pulling out the scale to provevto her husband how she wasn't kidding as to why she couldn't "keep up" with him in all the delicious vacation choices. So yes, a nutritionist can guide towards better eating, yet, can struggle themselves. So, in her case or the field in general, perhaps realizing that there is solid and sound advice despite the real, valid struggles in life's practice?
