I drink out of the same mug all the time. If it breaks, my life feels jagged for weeks, while I settle in with a new one. I can hardly bear to use forks, spoons, and knives that are not of a certain pattern that I'm used to. And pens... I'm a writer. I have a lot of different pens, but they must be pens of a type I approve of. I use fountain pens almost exclusively, loaded up with Noodlers ink, which is the only kind I use. And I am only happy with certain fountain pens; I hate Montblanc, for example, but love Pelikan and Noodlers new pens, and the Platinum ones converted as eyedropper fillers are nice, cheap alternatives. I feel better just holding one of these pens in my hand, looking at the ink glistening inside the barrel (I prefer pens that have a window, or, better yet, clear demonstrator models - although I'll make an exception for the Noodlers ebonite pens).
With just about anything I use, I have a specific preference / range of preferences, and anything outside that makes me uncomfortable. I get upset if I can't find the exact model of toothbrush I'm used to using. I cling to combs, even when a tine or two breaks, until I can find one that feels right. I have to use my shovel. Only my keyboard feels right. You get the idea...
For most things, it is one very specific item or model that works for me. For some things I use all the time - pens, notebooks, that sort of thing - I do have a slightly wider range of possibilities, but what I use must still fall within that range; I can't use just any pen or any notebook. Not even just any fountain pen.
I have pens I've bought to try out that I can't really bear to use. Actually, I used to only use one pen, always the same one, but then I got nervous, and wondered if I'd be able to write at all if anything happened to that, so I forced myself to get used to a few other types. I do this with writing; pens, paper and notebooks, applications on the computer, but not really with anything else. That is about as much flexibility as I can stand.
