While it's nice to have a theme when you collect (as it can help to keep your collection streamlined and organized,) from your initial post, I can see signs of you being a completionist, which is something you might want to exercise with caution. It's a double edged sword that any collector who has been doing it for long enough will tell you has it's up and downs.

On the upside...there is a certain satisfaction to having a complete collection of anything. It's a labor of love, and a lot of hard work, scouring the internet, flea markets and trade shows, and stores, and it pays off when you view the big picture of it all.

That said...on the negative side, where being a completionist will bite back is in the most obvious spot...your wallet. It's easy to lose track of your purchases, and unless you do extensive cataloging, easy to purchase duplicates without realizing it. Also, there will be times where you will often find yourself overpaying for something you really don't even like, be it at a toy or collector show, Ebay, or local retailer, simply because you "have to have it, or your collection is incomplete...." This happened to me on more than one occasion, and while it's nice to complete the collection, it's really deflating to your bank account. I used to collect Super Hero Squad figures myself, and was a completionist in every sense of the word, but I can recall facepalming myself on a late night many times after purchasing a figure off of Ebay simply because I could not find it anywhere else, all the while telling myself..."I can't believe I just spent 50 dollars on ANOTHER repainted Iron Man....but at least I got Tiger Shark!" (as if that justified my purchase, especially when I didn't know or care anything about the character in the first place...)

And that negative only lies on the buying part...nevermind the days (not to mention time and gasoline) spend searching high and low for things that you don't have yet. It can quickly turn collecting from something fun and passionate, into something more of a chore. While I'm still proud of my Super Hero Squad collection (of which, I'm only missing the Iceman/Beast holy grail two pack) I look back upon it as a learning experience, that for a while greatly soured my love for toy collecting as a whole, and it is something I will never be pulled into again.

The main thing with collecting for me personally now, is to enjoy myself, and get the stuff that I like most. No more overpaying for something simply because it'll fill in the spaces missing in a collection. And since then, it's been far more enjoyable, even if my collection is a bit more scattered and all over the board. There will always be stuff that you can start collecting and enjoy, but only if you continue to love and enjoy doing it. =)
