The act of discovering something or someone is actually not one-sided. Someone has to be willing to uncover (a part of) himself for us to discover; something has to be uncovered by nature or by sequences of events for us to discover.
In other words, people choose what and when to let us know. On the chance of someone/something being un(dis)covered accidentally or by force, there will always be a layer or two we cannot seem to get through. We can never coerce people to completely and truthfully open up. Opening up is rather an act of choice.
For instance, I am yet to be a good writer, but I am willing to un(dis)cover that part of me. I do believe that discovery is something we start from within, then only we can discover the rest of the world. So, let us.
