I want it all.

If my precedent post was about the effect Media has on the buyer, i must turn now to a similar yet different habit that plagues the person looking to purchase any art item (music , movie, comics...) in any form.
The completism.
The completism is that thing that push us to buy EVERYTHING a guy did, all his art, all the music he did even if it was just a small guitar solo or a singing on a single track. You feel compelled to have everything, to satisfy an urge to possess or even a sure method to explore all the facets of an Artist in order to comprehend his work or well, Him.
Mind you, completism is a good thing on some accounts. It well helps the guy you support live and create more and it also lead, by the ways of multiple works, discovery of other artists.
I started small but I ended up discovering many bands by just following a bunch of creators I liked.
In that completism is a good thing... but it has also Major drewbacks.
First and foremost is the fact that if you buy everything at least read it and enjoy it.
If you start reading something by alan moore you fell is crap event after 10 reading then ditch it.
Matt Wagner (of grendel fame) used to say that it's first 3 issues of grendel would never have seen print as he thought they were crap. Pression made it reconsider his word and he did reprint it. Interesting historical document but let's face it... Art sucks, storytelling sucks, story not even finished. After reading it I could understood what he meant and wanted.
So do you need to have everything (if possible money and time wise ?) ? No we should limit ourselves to things that makes you really feel something (good eh ! Not feel bad or disgusted ^^).
There are so many things out there to see, hear, read you cannot bother to keep on reading/ seeing/hearing things that leave you cold.
You can skip issues of X-men... Yes you won't have the complete collection but at least you won't have a longbox of comics you never read and just keep because you need a complete collection.
It does not matter if one thing is a classic to have if you do not enjoy it.
Feel free to buy the next thing your artist did because you like what he does most of the times and you want to enjoy some more stuff from him.
And then, ditch it if it sucks.
Yes you may have holes , you may miss numbers, records of else but hey if you have it but do not use it... What is it for ?
