Your way of doing things is a direct result of the way you think. And if you are thinking "from the outside in" you are letting what you see, feel, hear, taste and smell—especially the "big three", hear, see and feel—dictate your actions. In effect, you are not really thinking at all, merely reacting to your environment.
Is that such a bad thing? I don't know. I am sure that if I was in the middle of the road and I saw a car approaching fast, I would surely want to get the heck out of the way. And fast!
Still, the vast majority of people today let their thoughts be guided by the newspapers, the evening TV news, friends, neighbours and even family. Opinions are the cheapest commodity on earth!
Think about it.
