I see some people who don't care about these thing in the gym. Usually they just wander around without any kind of system and spend most of the time chatting. I guess they still feel like they accomplished something.
I however believe that if you don't measure your progress you are likely to have none.
I don't log anything, and I also don't wander around chatting. I show up, push myself hard, and then leave. But the types of workouts I do are guided, for example I did taekwondo for four years, and recently switched to doing "boot camp" workouts. I find it is much easier to exercise when an instructor is telling me what to do than if I just show up to a gym full of equipment and then have to motivate myself to do something with it. If your workouts are self guided then it makes sense to log what you are doing so you can keep yourself on track.
I see these types of people as well, and this is probably true for most people. I guess I just don't need goals when it comes to fitness to stay motivated or make progress.
