Querying?

I've never thought of traditionally publishing, never.  
Which is weird because I'm sure that's the goal of most writers, being on authortube has brought it into my mind.  Why not traditionally publish?  (or try anyways.)  I've always assumed it was this impossible intimidating vortex of being rejected.  Or being accepted and paid very little while waiting years for your book to come out.  But the closer I get to finishing MB the more the idea of it intrigues me.
This maybe premature and I might change my mind but I think I'm going to start querying to literary agents.  
Yes, to be traditionally published.  
This is a huge thing for me because I've never thought of doing it, I've been adamant about self publishing for years, but why not?  Why not try?  I have nothing to lose in the process except being told no which is life.  Mean Boys deserves the chance to be traditionally published so it can get into the hands of as many readers as possible.  So I've decided once I'm done editing and getting the opinions of beta readers I'm going to begin querying.
This is huge but I don't think I realize how HUGE it is.  Of course if querying fails I'll go back to my original plans and self publish.  I wanted to make this post to get it off my mind so I can focus back on editing. 
I'm terrified but excited to try.
