Restrangled : What we can ask of ourselves: What have I done to contribute to my neighbor or fellow human being?"
This have something to do with "Life is what you make it" we are not alone on this earth and just thinking about ourselve is not really appropriate. So life is what you make it (should not implying sucess) but how we can help others.
this reminds me somehow a very nice movie "A BETTER WORLD"
Now for instance if someone got a chance to becomes a surgeon ... I guess he can do a lot others and himself as well for money making and helping for free (free health care) ... but so does and can help any people who works in this area at every level.
