Painting the house
This is a somewhat acceptable job if I was made to do it. But I would strongly suggest that before you even deliberate painting your house you must read up or learn from reliable sources about the nuances of painting the walls properly.
The previous house where I shared my room, I had painted one part of the room that I stayed in and had not applied a coat of primer to the wall before applying the paint. In course of time, there was flaking on the wall and it needed to be sanded. I know now that applying primer is as important as applying paint itself.
