this is the best time for some thing--
you can use it for self-realization..in meditation..
you can read good stuff of your interest..,
you can do those things which you want from so long but didnt do yet.
and if you have partner,friend who are of your interest then you can do talk and explore things accourding interest,
in short i can say personaly that spring is the best season..i love it and my mind works fast and stays cool in this time :-)
