Please help with my incessant spinning wheel of death!

I have almost always had the spinning circle of death… Almost the whole life of this late 2011 15" 4 GB mbp. I just can not easily use this computer anymore. It takes so long to do anything. I need to exit all apps but the one I am using to make it work. I have to restart is almost daily to make it do much. So frustrating! Please help!

I already tried a disk repair under disk utlility with no issues shown.

I read on another post to run an etrecheck app and to post that info. Here is what it says.
