You can do anything you want to do, what do you enjoy doing?
Myself I have a degree in computers and networks. As well as 25+ years of knowledge working in the restaurant business and running a line as a cook.
Right now I am studying to take a USPS Postal Exam 473. I'm going to do a career change with a bigger company for chances of setting up a retirement fund and getting a bit more money, that I can't seem to get from working in the Bar/Restaurant Business.
If a company got rid of you because you were 'too deaf' you should have sued them. It's against the law for any company to fire anyone, regardless of their disability.
