Man working on multiple screens
7. Inability to multitask
At any point in the day, I'll be doing three or four things at once. Sometimes this approach is the only way I can actually get everything done in time. If you insist on tackling one task at a time, IT is going to be a tough career for you. Certainly, non-multitaskers can succeed in IT but life will be more difficult for them.
8. Corporate ambitions
There's little room on the ladder in the IT department. If you have dreams of climbing it and perching on top, you might want to prepare yourself for disappointment or consider a different field. Some IT departments do offer promotions, and you might even climb your way up to CIO. But if you really want to be a CEO, IT may not be the best place to start.
A man who hates technology
Strangely enough, I know people in IT who actually hate technology. If you consider yourself a technophobe, working with software, servers, desktops, switches and routers might be unwise. It's perfectly possible to work in a field you despise, but the resulting level of frustration might shorten your lifespan.
