My friend been working in the IT industry for years, and in that time he seen lots of issues, fixed lots of problems, and watched technology come and go. For that time he realize that working for IT is so hard, you need to upgrade your skill, have more knowledge and fix any issue that came up from different devices. Like or not, he do that. Even it has new technology that he didn’t know.
I think that make sense. In IT industry you need to upgrade your self. Read more and do more. If you insist not to upgrade your self, believe me. Everyone will watch you as legacy, an old technology.
