You study engineering, you can go into any other fields next
time... I've got friends with engineering degrees working in
business companies and banks... However, business graduates can
never ever be an engineer...
You study tourism and you're most probably stucked with that choice
alone...
Get what I mean? The scope of jobs available to you is rather
limited if you choose tourism...
But at the end of the day, I would advice you to choose something
that you like and have interest in... No point thinking of your
future and taking something that you dont like and then doing badly
for it....
