Learn, unlearn and relearn

I've read an interesting article today. And the thought that keep whirling in my head is "learn, unlearn and relearn".
It's simply so true that we are taught of something and if we want new breakthrough, we got to unlearn the thing taught and relearn again, in order to get a new perspective of it. Come to think of it, it seems like this message is being passed on not only in our working environment but also in drama. Have you ever noticed it?

We are always taught on following certain method in order not to get things done wrong. We fear of mistake and as if it is plague, we try our best to avoid it. But aren't we were also reminded of learning from mistake? If we are afraid of making mistakes, how are we going to get wrong? If we don't go the wrong way, how are we going to learn?

Are you the kind who need to check and confirm every single detail of the direction before starting your journey to reach your destination?
Or are you the kind that just need a rough idea on direction and just stumble along your journey to reach your destination?
Which one of it is you?
