I assume you mean "negatively affect"?
B/c I'd say my frugality affects my productivity positively. By removing the focus on buying and maintaining shit, I not only free up time, but mental energy. I'm better able to prioritize only doing what I really value, and as such, I'm more invested in what I do, do a better job, and overall consider myself more "productive" in a truly meaningful way.
The tricks I've found to decrease time on frugality itself include: (1) buying/using less (eg., limit what has to be printed at home so I'm buying ink way less often), (2) setting up systems as much as possible so that I can put in the work once and not do it again (eg., we use refillable ink that I order online. It's far less expensive than any deal I've ever found and I can just order it online in 2 minutes. Also, each refill fills several cartridges worth, so it lasts forever. Now that I've found and established my "ink system" I can spend a grand total of 5 minutes a year (if that) on ink purchases). I try to do the equivalent for as many areas of my life as possible (eg, automated payments, deciding what products are not even needed and never buying them again-like shampoo and styling products, deciding just not to do certain things at all-like sending xmas cards, etc)
