"I've always been inquisitive of this world.
I've always been inquisitive about this worldI come from a multicultural background, and throughout my entire life I've been fascinated with all of the diverse types of cultures and beliefs.
... it's better you describe about your multicultural background a little bit more... I think it is a good point to show that you've got some unique exposure.
I've studied atlases and scoured the internet in search of information about the planet for as long as I could remember.
You idea does not flow properly and I cannot get your idea... I guess you better re-phrase this line :)
You talk more about travel experience... however, very less is spoken about what makes you unique.... I think that's the point you start this essay.
