my Mac seems slow / sluggish.. the icon spins around and around when I'm trying to do something all the sudden?

Run the Apple Diagnostics to see if any hardware issues are detected.
To look for possible software issues run EtreCheck and post the report here using the "Additional Text" icon which looks like a piece of paper. If you give EtreCheck "Full Disk Access", then it will include more information including a summary of the recent logs which may contain useful clues.
Also, disconnect all external devices in case one of them is causing the problem.
