"apparently it's not a good thing?"
It's fine and part of normal computer operations.
Tell whoever told you that it's not a good thing that I said they don't know what they are talking about.
The data that is stored in the pagefile is rarely accessed according to your PC usage. That rarely access data is sitting on your hard drive instead of in your ram. But this is the same for pretty much ALL windows computers unless you get LOTS of ram and turn off the pagefile but then you could run into memory errors if windows wants more memory and it's not available.
Right now 16GB is in my pagefile size. But my system isn't even using the currently available RAM. (Currently only using 3.2GB out of 16GB)
