Look, one of the best controllers I ever had the privilege of working with, couldn`t spell worth a bean. Being in ATC, everyone took the p*ss out of him occasionally (just like I`ve had to endure plenty of the same for my shortcomings). He accepted all of it good naturedly and gave back some cr*p in kind. If you want to come into ATC, which is a great career choice, you had better get used to some fairly robust treatment. In an operational environment, there won`t be too much time spent by others considering the fragility of your ego.
Good luck, the advice was meant kindly.
