Is it wrong to love everyone equally?

I'm just curious as to how people perceive love and its role in everyone's lives. 

It's often said  that you should only love people who deserve to be loved, and 
I have often heard that you should love everyone without restriction. 

I am an easy mark... I love easily.. 
Sometimes I  get burnt by the ones I love.

I guess I often get hurt by those I have let into my life and come to love,
because I am quick to make emotional relationships.

I don't want to necessarily start a debate. I'd just like to hear people's opinions.
