I usually don't count the whole sum of anything, I usually think that I have the money, what else would I do with it. Like, if you buy a 2,000€ computer, you have that 2k it doesn't appear magically from somewhere just to buy a computer, it's not that you wouldn't use it for anything else, that your bank account would forever be that 2k heavy if you didn't buy that computer.
I have the money, I use it, the world keeps on spinning, I keep bitey happy and he doesn't bite me.
