Fill the pot with water, add a bit of salt, throw some chicken parts you like - legs, thighs, breasts. Important: chicken parts must have bones in them, otherwise soup will taste really bland. Boil really slow for 40min. If some sort of foam starts floating in pot, take it off with a spoon, it will make soup clearer. As it boils, clean and cut potatos, then carrots (as small as possible). Throw them in and boil for 20 or so minutes. After adding veggies, wait for 10 minutes and taste for salt. I like it medium-salted, some people like it unsalted. In the last 5 minutes, cut dill and parsley (dried, fresh, frozen - whichever you have) and add. You can also add stuff (bellpeppers, cabbage, spices) and remove things you don't eat. It's light and really easy on stomach.
In general, soups are easy to cook and eating a bowl of good hot soup can get you really comfy when the weather is rainy and it's cold and grey.
