I do not know if this is related , but I think i have exchanged physics and mathematics attitude from another 'me' in a parallel universe. I wasn't very well versed in math or physics yet i had chosen engineering i was determined to finish the stuides. At times I lied on my bed, watching my desk and thinking 'he is working' , in a matter of weeks I developed an excellent physics inclination, just as if I was gently pushed to study stuff. Later I graduated , but i think that 50% of the merit has to be addressed to the other 'me'
