As much as our brain has limitations to what it knows and don't know, we need to soak up as much as possible and again, THINK. Observe and use rationality. Intuition is also there for a reason. Have your own opinion. And even then, you still have to do constant evaluation when your receive new materials. This is how we avoid being an "extremist" towards and idea. Many people are too obsessed with what they think, or with a pack, they heed blindly and it doesn't define a first-class thinking especially since we always talk about being a developed citizen. Everything we do have impacts, not only in a small community but also contribute vastly at a global level since we live in a limitless world thanks to the Internet.
I am still learning to answer questions precisely when it involves me expressing my opinions because there are times when I couldn't really express what I want to say. But recently I discovered that I also need to know what to say which I call 'selective expressing'. Questions can sometimes be manipulated to suit our needs instead of the interviewer's and still not be out of context. It is quite difficult thinking and talking at the same time but I really do encourage us to try that because day by day, I hear more and more bullshit up the Internet. I feel like we put less thought into things but more emotions. Or maybe likes and shares mean more than conveying a message per say *shrug*
