Teemo is your best choice, trust me. http://m.quickmeme.com/img/ff/fff1984ab78bcc6d9dc99d9fb126c3309d6425bb5043a8351b3a1d49375e0ed0.jpg
I started maining this guy because one of my friends recommended him because of his silky voice: http://vignette2.wikia.nocookie.net/leagueoflegends/images/d/d4/Taric_OriginalSkin.jpg/revision/20160404184243 Then I found out he was a closeted gay. That made me love him harder. Then this happened. http://cdn.idigitaltimes.com/sites/idigitaltimes.com/files/styles/large/public/2016/04/04/taric-splash.jpg And now I LOVE HIM AND NO ONE WILL EVER STAND BETWEEN US. NOT EVEN THAT FILTHY EZREAL. I make exceptions for Garen. That'd be a fun night.

Sometimes it's easier just to find the champions you don't want to main.
Solution: Main ALL the champions!
Wait.. Your main is a reflection of yourself?
GODDAMMIT
I guess the stage is my canvas after all..
I chose my main at lvl 16, when I said, "who looks cool? OOOOOOHHHH bird. Bird is cool. I play bird now."
I had chosen anivia, and I still play her today (I have almost hit 200k mastery with her, I love her so much)
You could do something similar - just look around until you can find yourself the coolest champion, or a waifu, or whatever. Then get gud with him/her/it
Well I main Fizz and Ekko sooooo... maybe it's best to hide in the darkness from the atrocity within. OR EMBRACE IT
I mained Ashe for a while, then moved onto Tryndamere, Jinx, pre rework Quinn, then became a jack of trades. Right now I've been liking the adc class with Graves and Caitlyn. I don't know where I will go from here, but I'm sure I'll find a main someday.
Nothing is better than 
You dont NEED to find a main. Just be proficient with the game and how to play it and by extension the champions within it.
I hope i dont get hate for saying. Not saying its not fine to find a particular champion you can focus on, but theres too much emphasis on being a main of something to be good over just being proficient and consistent with overall play.

I Like To Go Where I Please
Have you tried
? I finally found my calling...
For me it was Jhin.
join me my child 
Then it's the perfect time to main:
