I'd say the biggest mistake people make is having no progressive overload. If you are progressing then that is number one.
Wiping yourself out and trying to incur a great amount of fatigue after each workout is only the province of the ignorant. Having energy after a workout does not mean you haven't done enough. On the other hand being tired after a workout doesn't mean you "overtrained". It is impossible to overtrain after one workout or even a week of workouts.
You probably shouldn't add any more workout days to your week but you probably could add more to each workout. But I'm confused because you say you do 15 total sets per workout? But it takes you an hour or an hour and ten to do it? It sounds inneficient. Either you're doing three exercises or so and taking too much time or you're doing a bunch of bodypart stuff meaning you spend most of you time going from one exercise to another only to use light weights and stuff that doesn't give much of a training effect.
The best thing you can do is write out your routine. Not just the exercises but the average reps and sets. Give your thoughts about it. Your progress if any. The more detail you can give the better. Until then we are speaking in generalities and I am making wild ass guesses
Training is not really a general thing. It is specific to each person and what they are doing plus what they need. General little rules about overtraining and all that other happy horseshit won't really help you develop an effective training routine. You gotta get into the nuts an bolts of it.
