All done ?? 
Have you all gone through the recalls of the question papers and made your mood bad in the past two days, finding out more wrongs that you expected ? 
Discussed with your friends and released that you made a mistake when he/she pointed out they got the question correct? 

I hope you must have dont it and I hope you must have wanted to hit yourself for doing that silly mistake !

So had an interesting question asked by a student "Why should I know the recalls and spoil the mood when they don't repeat (or repeats very very rarely)" 

Very logical question. But only tiny little problem is you are still putting yourself in the chair of a student. Not a consultant doctor !! Let's change the mindset and look at the bigger picture.. 

When you make an error and when you sulk over it, i should have not done this, when you get depressed - why did i mark this - There are numerous permanent connections happening in your brain neurons - relating unrelated things to explain why you made the error. And you let it go after sometime -But your brain doesn't, puts it in a non-erasable permanent storage. !

Try to recollect this would have happened in your life. You HOD/Professor would have diagnosed something super crazy -  all your department junior staffs will be like wow, he is just amazing. Someone would have asked "Sir/ma'am, how did you think of the diagnosis?" A genuine professor would have told "I don't know I had an hunch" -  You must have thought that guy is showing off and did not want to share how he did it. 

Actually no, the person was telling the truth - It must have been a hunch. But you know who made that happen. The INICET/AIIMS/NEET?exams/ward round "ERRORS" you made - who is sitting there silently and teaching you.  

Those mistakes must be screaming  "Hunch, my foot -  you scolded me 20 years back for making you sad - Now look you puny human, i helped you

And you recall your error and we get over it for that reason to have "The needed Hunch for future" So now go back with a smile and recall them and if you feel like hitting yourself for a mistake "Do it, hit yourself" - To make your circuits even stronger ! 

Keep learning, Keep smiling ! A very good morning!
