He’s basically saying to them to stop feeling sorry for themselves and don’t take for granted but appreciate the life you have because it can be way, way worse than what it is.
When I lived in the burbs, there was only 12 houses on our street and we all got along....Once every year one of the neighbors sent out invitations to all us gals to meet at her house for coffee and donuts and we will have a pity party...bring all your emotional crap and we will sit around, drink coffee and feel sorry for ourselves. When we are done we will all feel better and have another one next year, same time, same place. You can only pity yourself at the pity party....it was great fun...
