Reasons to say korbonos; a- instituted by Chazal ,
b- if one did not learn anything for the rest of the day it covers minimum chiyuv of chumash, mishna, gem.,
c – al pi Zohar it is the 1st of the 4 parts of shacharis that are kneged the guf, nefesh, ruach and neshama. (try getting thru the day with just a nefesh, ruach and neshama) on the other hand maybe not a bad idea that last one.
