Help with Lighting

I am the shittiest light creator out there. I know how to use the light_environment and all that, but I cannot make the lighting in a room look good for some reason. It always seems pretty wrong to me. Could someone lead me into a very detailed, “lights only” tutorial? Thanks to anyone who helps.
