None of us are hungry, none of us are living in the streets, none of us are unloved. We all have things that keep us going, and when you think about it hard enough, it takes a lot less will and determination to simply get up and decide you're going to have a great day. Keep a mental list of how many times you get asked "How are you today?" or "How are you doing?" and what your answers are. I'd be willing to bet that if you were in a really bad mood, but could find it in you to manage a smile while replying "I'm doing great!" enough times, you might actually come to believe it. Keep another list of how many negative things you say to yourself and to others each day, see how high it gets.
I could complain about a lot of things, but I am choosing not to. I figure that as soon as I start, I let that bullshit take over and it defines who I am. Well not any more. I have clear examples in my mind of who I don't want to be, who I am not, and who I choose.
Life is great compared to how a lot of people live, by choice or by circumstance. I'm done with as much misery as I can help, and the rest is just going to have to work itself out.
We're all so mean to ourselves and to each other, and it's really sickening. We spend far too much time making fun of other people's miseries that we don't give any thought to making fun of ourselves sometimes and laughing it up more.
Heal it up, make it better, or move it along.
