Go with the flow. Think and use conventional flow notation unless it's necessary (unlikely with normal circuit theory) to understand the actual physics of the component.I'm afraid I may not be stating my question clearly enough. It's not necessarily the order of the components, but the order of the components relative to the actual electron flow. If electron flow is opposite conventional flow I'm having trouble understanding how current makes it's way around the circuit (for instance, without being blocked by a Diode that's in the circuit. I guess I'm thinking like a technician/troubleshooter would have to think?
