I was about to bring this up. When I was in college 15 years ago learning
this there was conventional current flow which goes from + to -/ground. And
there was electron flow which goes from -/ground to +, because that is the
directions that the electrons actually move from atom to atom. But since
schematic symbols were created with conventional flow type thinking (from +
to -) that seems like the way you should think. You don't want to start
questioning what direction your diode and transistor symbols should be
pointing if you are drawing a circuit.
