The only sorrow I had is that I failed in my exam previous year ! I used to top during my school and +2 days  , It made me enter into a good engineering college . 
I always wanted to to explore new things , one day  I've been exposed to Network Marketing by  my friends . I loved the whole new idea and engrossed myself completely in doing it . Of course I've succeeded to some extent but the tyranny is that I failed in my academics . I could only perspire but not respire seeing my results .

This particular event haunted  me day in and day out , I've passed through many sleepless nights . I really didn't understand why I did so and of course I'm afraid of failing . Darkness captivated my life and days passed .

The only thing that helped me during this down time  is this book named " THE MONK WHO SOLD HIS FERRARI" . It really rejuvenated me . I never forget this experience in life . The most important lesson I learnt from it is that " One should never neglect some things by engrossing in other" . Every work is important to us , later we shouldn't have a regret for doing anything wrong .

Sometimes I feel good because I've learnt a good lesson from it !

Thanks @shello , you made me nostalgic !!
