My Advice
Mate, i am someone who does recruiting and doing well in the job. Today I opened the applications for a vacancy we had and 284 applications. 90% mentioned computer studies, Diplomas, HNDs, BCS, ACS and etc. I was actually fed up seeing that. So unless youa re planning to go a long journey in IT, do not change. Coz what you are doing is better than IT. Also long lasting, knowledge will not obsolete fast and no threats from new comers.
