I don't know why, but I have a lot of trouble buying new stuff.
I don't mean stuff that I need necessarily. But new versions of items I already own. For example, I only recently got rid of a jacket I've had since college. I've been wearing the same shoes for two years (although I have replaced the insoles). I do have new clothes, but only because my mom loves buying me clothes.
When we moved to this area with all our old furniture gone, we bought an apartment-full of stuff at this college store nearly a decade ago, which we assumed we'd replace over the years. We still have almost all of it. Ditto with all my pots and pans and dishes, aside from my one big frying pan.
I don't know why I'm so adverse to buying new stuff. I guess I always just feel like why should I replace a perfectly good [insert name of object]? I don't really enjoy shopping for new things. Honestly, it sort of stresses me out. I only replaced my awful laptop because it wouldn't run a program I needed for work.
But you'll be happy to know I do replace my toothbrush on a regular basis.
