Also, you can but a handemade quotes that you like or motivate you ( you can find ideas on YouTube or pinterest) that will give you a good vibe for your living room
Also, a string of lightbulbs along the walls can make a dark room nicer. Maybe only for one or two walls, the darkest.
And a lamp to light up your favourite painting/poster?
