The scope is very big. Any things when you decide to do is really need to think the result. What if i do this way? What if i select this way?
Mostly, most of the people do not think too much about the consequences, and directly doing what they like. Maybe the consequences at last will be horrible...
So, the prediction is needed. We all have to make a lot of assumptions to every cases. In my life, i always predict the result if i was done the relevant action.
Last, i hope i can be trained and become a mind reader! Just like heroes - Matt Parkman. It will be more easy to let me do the decision.
