Everyone brings some good points to the table but you have to realize, you can write about proper shifting techniques all day, but driving a stick is all about feel. If your shifts are smooth and your passenger doesn't realize that you have a stick, then you are doing it right. If their head snaps back and forth like a bobble head doll, you're doing something wrong. If you get out of your car and something smells burnt, you're doing it wrong.
