 ## Why you should care about memory usage
 
-* **Over-requesting memory** may cause your jobs to **wait in idle** for longer than needed, since HTCondor needs to find and allocate these larger resource requests for your jobs. Additionally, CHTC's HTC system is a shared resource, so we encourage you to be a good citizen and only request the resources you need for your jobs.
+Because CHTC is a shared resource, correctly requesting the resources that you require for your jobs to function ensures that both you and other users have a good experience on the system.
