Right!

As every kid wonders in his exam hall with ink blotting his answer-script, every mother guesses the right amount of sugar in the tea,every youngster wonders about the pick-up he must use, every father worries which expense to cut down, every grandfather, the apt work to busy himself....

there is a loud BLEEP!
"I'm sorry but you are so very wrong!"

Now, if I may ask, what exactly is right???
Everybody has a definition for what is right and everybody else has reason to believe otherwise, but the ultimate judgment lies in the vicious hands of the critical second person. the mind that functions in a unique way distorting facts according to varied levels of knowledge, absorbing and discarding to one's own discretion the facts presented and finally forming an opinion. It is now the turn of the third person, to whose ignorance did this presentation of reasons fall prey. He receives a biased version of the actual datasheet, and on goes the same process.
In the system these days, there is a congenital privilege provided to some, 'The Haves'. Rich in a variety of ways pecuniary, health-related, emotional etc.
Basically, they do not bother whether somebody thought he/she was wrong, ideally this is the only solution one can give to somebody that fails to take-in criticism. Then there is this other kind of people who take -in criticism wearing the positive glasses, yet again employing ignorance to the negative, these are the ones that change themselves to fit-in. Lastly, there are those that take criticism to the heart, upset by it, they take the most drastic steps.

Now for those of who are not good at the 'Algebra of Life' I'll give you the relation between the above 2 paras. All the people that are now in a phase where you are awaiting somebody's approval, be it your parents, teacher, children, wife, husband, brother, sister etc. please let-go take it in your hands, do what you think is right. if you're wrong you'll repent but learn and if you're right, well done! But remember, people are not inclined to criticise your decision-making-skills but to preach you from their mistakes. There are positives and negatives of this too but its upto you, what kind you are: self-learner or blind-believer.

Lastly, the best you can do to combat this is prepare the heavy artillery, to shut everyone up. for e.g. study well, never lie unnecessarily, never commit to misdeeds and justify your reasons well. You'll never falter in convincing the second-person.

This is for all those who are going to appear for the exam-of-their-life(take it whichever way you wish).

Best Of Luck!
