Do I regularly listen to my own interpretation? All of these questions can be answered more accurately when you don't have to touch and listen at the same time. Since we all hear other people play, recording yourself and listening to your own performance gives you a certain context that is very important for constant improvement. If you have a laptop, chances are you already have the ability to record yourself well enough to help you examine your game in greater detail. Just make sure you practice each week so that in the next lesson you can learn even more, this will make each lesson much more productive.
If you are new to learning to play the guitar, it is important that during your first lessons you evaluate your level of interest in the instrument. I recommend that most beginning guitar students start with a 30-minute class for several reasons. Similar to 45-minute lessons, teachers generally value a 60-minute lesson, so it's the best overall deal for the student where you're paying a price that maximizes your time with your guitar teacher. When selecting the length of the lesson with your private guitar teacher, consider the cost, the level of commitment, your experience with the instrument, your ambitions with the instrument, and what feels right.
In your first few lessons, your teacher will give you a lot of information on a variety of aspects of learning to play and practice guitar effectively.
