Knowledge is just Knowledge unless it's connected to Wisdom. You may consume good or bad knowledge, it's still just knowledge. many have plenty of knowledge yet still don't know what they are doing. All our issues comes from, not a lack of knowledge, but rather the lack of wisdom to process this knowledge. The issue then becomes if one understands that he or she don't know the quality of their knowledge. Also, if they even know or understand how to use such knowledge. Most in our society don't know what they are doing even with knowledge. It dosen't matter if you're a  Bum sleeping on a sidewalk or the CEO of a major Legal Firm, without wisdom as to how to use such knowledge, you still don't know what you're doing.
Now, another issues that we all face is thus; The hardest thing for a Man or Woman to admit is that He or She don't know what they are doing at any given time! Most people feel that if I let them see that I don't know, I'll be looked down on.You may be a Doctor, Lawyer, Teacher,Father or Mother, if you can't admit that you don't know what you are doing then you can't make it right! It takes a real Man or Woman to just stop and say, God, I really don't know what the hell I'm doing. Once anyone can reach this stage in life, then they've reached the first level of Enlightenment.Now one is free from the burden of trying and failing only because you just don't know what you're doing.Also there are those who don't know that they don't know.
It's no Sin, Crime or Less of a Human Being to admit that you don't know what you're doing! Once you can admit that you don't know,now you can start learning how to know.
Peace...
