How to put things off you can’t do anything about now

As I am working myself  through my undergraduate programme in landscape architecture and planning, I am already thinking about which master to take. There are a couple of options I find intriguing:

Coming to a decision is only part of the problem. It’s still more than a year left until I actually have to make that decision, in fact, it won’t be before December I can apply to anything. There’s absolutely nothing I can do about it right now and yet this pondering is nagging my mind to no end, taking up way to much brain power which I rather invested on other things. So today’s big question is, how to put off something that is bothering you, but which you can not do anything about at the moment. Basically, I want to put it into a mental hold-file, erase it from my mind and follow up on it in autumn. I know how to do it with a file on my hard-drive, but my brain doesn’t work like that. Any suggestions? I might continue this article whenever I came up with a solution, which I don’t at the moment, because…which master programme should I take again?

edit, half a year later: Over the course of the last 6 month that list expanded to about 20 extremely interesting master programs I’ve been considering. However, coming back to University in fall made me realize the advantages of my current program. All those other masters, tempting, but not better suited for my overall goal to plan sustainable communities than the course I’m already taking. It’s like walking down the aisles in a department store, when all the shiny products left and right of you are grabbing your attention while their’s only one product in the whole store you’re  actually need. Ehh, I forgot how much I hate department stores…
