Everyone who owns a house needs to at least develop some DIY skills, or pay through the nose for every little thing that needs fixing. I didn't know much until we bought a house. I once even had my step dad help us when we needed to paint some fucking walls in the apartment. Not my proudest moment... I generally think it is mostly down to confidence. Once you realize it is ok to fuck things up, to a point, then you are alright. You learn from it, fix it, have learnt something new.
