I think in times when we feel worthless about life being reminded that there are one or two skills we are good at can help us feel better about ourselves. Because everybody is good at something. 
List any skill you have like cooking, repairing vehicles, using computers, first aid training, art, etc.
My one skill is that I'm a pretty good cook and know my way around a kitchen. I can cook all kinds of things like baked chicken and porkchops, cook hamburgers on a frying pan, fried chicken and porkchops, meatloaf, chicken alfredo, chicken and rice, chicken and dumplings, mac n cheese, lima beans, field peas, eggs, bacon, sausage, cinnamon toast, and I can even make a delicous baked ham using an aluminum tent and a little bit of water.
