Growing up under this influence, I subconsciously learnt that there was no clear division between good and bad people.
Bad people are "bad" for a good reason. In one of the Hongkong movies I watched when I was in primary school, the vicious guy who robbed the bank was shown in the next scene nicely talking to his blind grandmother, and giving her some money (from the bank loot). His actions to kill innocent people at the bank should have him condemned to the last level of Hell, but it doesn't mean I can't feel a little sorry for him just because "at least he was nice to his Grandma".
Similarly, we see that nice people have their dark side. Batman, Spiderman and also Iron Man. All had their mortal weaknesses and mistakes.
Some of you may read about the 6 months I spent at the age of 18, reading all sorts of "Be Happy" books in the library just to correct my mindset and make myself a happier person. One of the lessons I learnt was never to judge people by what they do. It doesn't make me an unbiased person, because let's face it - everyone, no matter how holy or kind, has some form of biasedness or preference when it comes to people.
For any person you are having a problem with, be it your demanding boss, your possessive girlfriend, your whimpy colleagues, or your naggy mother, ask yourself this GOLDEN question.
Recall an incident when there's something good about this person.
The boss may be demanding, but from your conversations with him, you at least knew that outside of work, he's a caring and endearing father to his daughter.
The possessive girlfriend have some trust issues with you, as if you are going to stray anytime with any girl on the street. But you remembered a time when work life was hell, but she was there on the phone for you every night, to hear your never-ending complaints.
The whimpy colleague complains about the smallest issue going on in the office, even though everyone in the office knew the problem lies with herself. But when this whimpy colleague gets you a cup of coffee seeing that you are working late, for a while she seems like an angel.
The naggy mother keep repeating the same issue that has gotten you frustrated everytime, that you wonder if she's just trying to piss you off. But then she goes out of the way to make you herbal soup whenever you are sick. And then you realised, that she loves you so much.
Once you have helped someone you dislike to come up with a past incident in your mind on why he is really not that evil, you will start to realise that the hatred/displeasure will start to ease. And that's when you start to cool down, and even help to think about "good reasons" on why the person did that "bad thing".
And you start making rational decisions on your next action, rather than boycotting the person, or slandering him in front of your friends.
Practise make perfect. For all you know, soon your enemy will become your friend with your newfound judgement of him.
And that's the reason why I am always popular, with both people are who popular or unpopular.
Yes, the world will become a better place, and you get things done easier with this newfound contrarian mindset.
People are not binary - 0 for bad and 1 for good.
Everyone is 0.5, if only you look harder.
