It is very important to have your own opinion in this world ruled by few. Not having a personal opinion is almost degrading and in some way is like giving up.
Even in fields of exact sciences it is encouraged to have your own opinions and views. Accepting the facts is one way of "learning" but not the best one. Learning through shaping your own views of nature and coming to conclusions already discovered by science is a much needed process of learning.
Being wrong is just fine if you are ready to change and develop and most importantly learn through your mistakes.

Great post as always!
