My opinion.
It's not for someone else to decide on what you going to choose for your education which also will be your future.
Pretty sure you deeply inside know yourself what you want to do and learn.
Other suggestion usually drunk people tell truth and do things they always wanted to do but couldn't do being sober because they are too afraid. So get drunk and apply for a course that you think is the best while you drunk because then you really know what you actually want. ( Don't take this for real but yeah that could work really ) anyways if you don't like the course you will apply for you are able to change your course in first month of starting your education. ( Pretty sure you can do that at least I knew I could when starting my education )

Get drunk and apply for courses? Ha.

Spoiler:

He should get drunk and go to said courses, too.
