Another important thing to keep in mind though is your body language. You should be very aware of this because it can either reveal things you don't want people to know or if done right can lie to them. For example, if you're in there against someone trying to push the pace you want to be careful not to give them any cues that you're taking a mental break. If you have a habit of say hopping back, shaking your arms out and taking a second to reset after an exchange, a good pressure guy can sense that and will start pushing you after exchanges to keep you uncomfortable and not let you get in your rhythm. That's him being a good ring general. You being a good ring general is you not resting right in front of him and making him be wary of engaging at all times. It's a lot about unspoken communication between you and the opponent. Not letting him know if you're hurt or tired or uncomfortable while doing everything you can to make him feel those things. A bunch of intangible things come together to make a good ring general.
