What is Preference?

I would like to begin the birth of my new blog with a question for all interested - where does the boundary of preference begin and end?

To place a sexual affiliation, I am a virgin at blog upkeep and am always open to suggestions (and now with my first post's abstract, I shall begin my view...)

Preference is somewhat affiliated with a highly intensified notion of what it means to choose something over something else. Now to simplify matters, overused-pronumerals X & Y shall be used to illustrate choice.
X is a possibility of interest for the subject and Y is as EQUALLY a possibility of interest. However a being should be endeavouring to isolate a possibility and choose it to be of interest for reasons none other than to see life move on. With X & Y (excuse the title of Coldplay's new album) as options, why does this subject need to choose; what is the compelling nature of these 2 futilistic terms that life cannot proceed without? But the problem is I don't know the damn answer to my own rhetorical question!

Political Preference
Sexual Preference
Economic Preference
Career Preference
Friendship Preference
[Any word] Preference
I am not here to bombard readers with all the different preferences life has in store for us but to inform all that life has created so many dillusions for me that I, personally, struggle with the meaning of life - to bluntly put my mental stability
