Hmm.. That's too much of a "calculativeness" you have there. Yes people sometimes stepped on your tail, and you need to strike back as introvert. If not people will think you're just weak for the rest of your life. But don't let the mindset of being impressive or I'm better than everyone to fool you. Be your trueself regardless of where the judgement come from. That's how you achieve true happiness and purpose in life.
