I am a maritime grad from NTU. Am currently doing shipbrokering. Yes, you would require a shipping specialised degree to get in. But probably the questions you should ask yourself before jumping headfirst are:

a) Do you have a outgoing personality?
b) Do you enjoy drinking with clients?
c) You must be able to work in a fast paced environment.
d) Do you mind working 24/7? Emails would be synced to your mobile and you have to check after work as well.
