Love is a feeling when you start liking the things you always disliked.
It is a feeling of self satisfication. A sense of completeness.It is different from lust, because in lust you look at only the physical attributes, in love physical attributes does not make much of the difference.
Everyone should fall in love atlease once!!! If you do not find a guy or girl, then better idea is to fall in love with yourself.
As they say, to love othera you must love yourself first!!!
