Don't plan all the places at a time .. make sure u visit the places at right time I mean visiting Manali in summers is the best time and similarly .. so plan accordingly and make sure u spend enough time at each and every place..
Travelling all over India may just sound very enthralling and fascinating but without a plan it can be a pain. My advise would be first check your proximity and then plan on a travel routine. Also the big cities can wait aim for the lesser known places as they would be soothing for your pocket too.
