Since the advent of the new budget, I have had to learn to use things up, make do with things I have, and do without things I otherwise might have bought. Not a bad lesson to learn, certainly. I have been learning that I resist using things or using them up because I worry that there will not be enough—that I will be caught unprepared.
I have been learning to tell myself that there will be enough. It is okay to use the last box of broth because there can be more (whether I make or buy it). It is okay to open the last bag of pasta because I can get more. I don't need to buy a new bar of shampoo until this one is mostly gone; there will be more.
And sometimes things work out in spite of my planning or lack thereof. A friend sent lovely handmade soaps and now I have enough. The sub shop down the street unexpectedly brought a box full of mini subs for the office and now I have lunch.
