Dear penfried,
It is so nice to hear some news from you after such a long time. I’ve got your letter and i am looking forward to help you. I know that you have always liked your music classes and doing sport and it is such a shame that you have to give up on one of them considering that you no longer have time for both.
If I were in your place, i would have chosen the music classes. In this way, you can become a music teacher sometime in the future and you will always know that you have a guaranteed job in case something goes bad at the other job.
Regarding continuing doing sport, you can always do that in your free time as a hobby . you Don’ have to see sport as necessity but an escape from the real world ,letting the stress away
I hope my advice helped you and you will consider my answear. Let me know when you decide what to give up.
Looking forward to hearing from you,
Irina
