"I personally feel like I've already won the lottery for all of the things I have no control over: living in a wealthy country, not having to worry about food or water, being reasonably healthy and having access to healthcare, etc."
Do you actually feel like you've "won the lottery" or do you just try to remind yourself how lucky you are? I've read a number of studies that suggest we internally compare our status relative to those around us. So while I don't have to worry about access to clean water (which much world doesn't have), I don't personally know anyone without access to clean water, so I don't really feel all that lucky about it.
Conversely, I don't personally know anyone with $100 million, so if I won $100 million in the lottery, I would feel quite lucky.
I guess I ask because I'm curious if you can actually "force" or reason yourself into feeling lucky, or if that feeling is dependent on your environment.
