Is Facebook something to have? And is? Likes on Facebook Something To Care About?

Well, almost everyone I know has it, I don't want to be a loser and don't have one. Like when I did have facebook I only got 14-18 likes on my photos. Does that matter? Cause I was always scared that when I did have facebook everyone was going to say something like '' you only have a little likes on your photos'' but I know a lot of people i'm getting a Nikon camera soon in the summer for my Graduation present, so I just really want to know like, is it important to have likes on your photos? Or who cares? Some people I know are really pretty and usually they get somewhat so many likes but some photos they only have 1 or zero likes, does it matter about the likes? And can someone explain to me how to get more likes on a photo thanks.

Added (1). Well what I have read so far on the answers I have gotten, I guess likes are not really important. Thanks Guys.

Lol nobody cares and if they do care about likes, they need to get outside! And facebook is a huge waste of time

Facebook is for no lifes, don't be lame.

It's important for people who are immature and think likes reflects on popularity.
