Thank you for your detailed posts and personal insights!
I will try to answer you with my Kartoffel-english (I sometimes have problems to say what I want to say).
I started studying electrical engineering because I am obsessed with guitar amplifiers. I still am. I own several old Marshalls and a few other, tube driven, devices from the 80’s or 90’s.
I already have an completed apprenticeship as businessman (I hope it is called like that, here in Germany it is called “Kaufmann”). It is very important to have an apprenticeship here in Germany, because otherwise you will most likely get nowhere to work. You can’t really do anything here without that.
After that I was not really satistifed with the job and decided to study something that I found interesting and is related to my passion for music and guitars. I mean, in electric guitars and especially in amplifiers, there is a lot of electronic.
In the meantime I got a job as research assistant in a very well known research facility here in Germany. I help to develop electronic devices, some devices I even develop on my own without help from other engineers. I really enjoy this and I am pretty good at it (I now do work which is done by engineers with a bachelor’s or even master’s degree), but it has nothing to do with music.
What I noticed is because of the really tough subject (electrical engineering is pretty time-consuming), I don’t always have time for playing or practicing. And I am extremely afraid that this will get worse when I am finished with my degree and start working as an engineer. Sadly I don’t really know how this is in other countries, but in Germany you go to work somewhat early in the morning (most people start at around 8 AM) and work until like 5 or 6 PM. On days where I don’t have to go to the university I work like that. And when I come home I grab something to eat and have to do some other things like cleaning etc.
Let’s say I can start practicing at 8 PM. On most days I go to bed at around 10 or 11 PM (I need my sleep ). And I want to meet friends and do other things like reading a book or something else.
I constantly imagine the future as “I will go to work and maybe, if I have time after working, I will do something”. That’s a problem here which many people have, but most people don’t have the urge to play the guitar several hours a day
And I don’t even have a girlfriend and/or kids at the moment, which I would like to have in the future.
My whole problem is: How can I fit work and music in my life?
I know people who stopped playing because they were too busy with work and family. Of course, every single one of them still loves music. Most of them started playing again after a long time, even after 20 years when they were in their 40’s or even older. But I don’t want to stop at all, I want to constantly get better and learn new songs/styles/things. That is what I want.
And I am afraid that there is no place for that in life.
I don’t think that I have the talent to do this professional (I chose the title somewhat wrong - I meant to play at a professional skill level, no to live as a professional musician, sorry for that), I don’t even think that I want to do that because I think it is possible that I would stop loving it so much, because I have to live from music.
But when I work as an engineer (which is really comfortable and well payed compared to many other jobs, many other jobs are far more time-consuming too because you sit in an office for a whole day), I fear that I don’t have enough time to play like I want to play. And this feeling of having no really satisfying options is, let’s say, very frustrating.
