Growing too fast?

Not in height of course but something else. This is about my development as someone who's been going to school for as long as I can remember. Now 23 years old and attending college in electrical engineering and majoring in power engineering. Suppose I'll get right to the meat of it. It's a project for this semester where we're going to measure how much the school could save on a working occupancy sensor in a particular location by measuring the power consumption of lights that are operated manually as well as the power consumption of another set of lights that work using an occupancy sensor that only requires you to change the starter of the room's fluorescent lights. Then we have this power analyser that's capable of not only measuring power usage (among other things) but also has memory to store measurements at a determined time interval. Before this all I've worked with has been this seemingly unimpressive tool. What's more, we're going to have to get to the wiring of the place in order to set the connections in place. There's also a lot of other stuff that had to get covered in preparation for this endeavor where some pretty crucial realizations were made. Been sparing you the details of that.

This all seems... too impressive to me. In the sense that I can't believe that most of it came from me. I've always thought that this sort of thing was beyond me. For my whole life I've been thinking that I'll be this complacent worker who's just going to follow orders and not make a fuss about anything but here I am taking the lead into the blind spots of people around me. Even my own blind spots apparently...

Maybe I'm not really growing too fast but more like I've been growing too slow. Everything was relatively easy-going up until now without me seeing much change in my own capabilities. I've always done well because no matter how advanced the material gets over time, in the end when all you have to go by are grades where you usually get around the same number, it's been giving me the illusion of being stuck in place as far as educational progress is concerned. Now that I'm getting well-versed in what's being taught to me here while I'm actually applying what I learn in a practical manner as opposed to just taking information in for the sake of readiness to make a test or exam... Well, I'm actually very impressed with myself to the point that it scares me.
