Everything I've read sounds complicated. In lighting the best advice I've heard is "follow the source." In other words- on a wide establishing shot you show where the dominate light is coming from, e.g. expanse of windows, etc. then compose your shots, (mediums/ CU's )whether it be bounced/softbox,whatever brand/mode-- BUT your shot should reference the dominate light 'source.' I hope I made sense. If not-ignore and bounce.
That sometimes can work. However if that is all you are going to use for light it is probably going to turn out flat and boring. That's what makes lighting so much fun is trying out different things and lighting to the camera which means not necessarily only lighting to source.
