When it comes to training with weights (what I call what I do until I am sufficiently prepared to stand on a platform and have other people tell me if I executed a lift to their satisfaction), the theme should and must be simplicity.
What you may find, as with many things, there is a connection between what works for lifting and what works for life.
Use the simplest method that works
Too many people are looking for the magic bullet. Pulling routines from anywhere that they hope will give them the edge they need. Take a step back, and look for the least complicated answer. You don't need to do 12 different leg exercises if you can't squat 400 pounds. This applies to everything you do, from cooking to statistical analysis. Apply it.
