When you've spent your adult life as a salesperson, a teacher or a fast food restaurant manager, you just aren't sure whether or not IT would be a good industry for you. Of course there's no easy to know this. I'm sure there are born techies, the creatures we joke about who took apart hard drives before they could walk and spent their college Saturday nights learning Assembler instead of getting drunk and dating like everyone else. I'm happy to report that's not true. In fact, if you have ever consulted a techie about a computer problem, you know there is a dramatic shortage of techies who can communicate to real people from their own viewpoint.
Some techies barely speak English.
So, even though you prefer a day at the beach to a day spent debugging Delphi, you may still have what it takes to have a successful IT career. Assuming you are willing to learn the techie stuff, of course. That doesn't mean you have to design motherboards in your spare time. You don't have to dedicate your entire life to computers, just be willing to learn what you need to know and to apply it on your job. Still, that doesn't mean an IT really is a good job for everybody who's willing and able to learn the OSI networking model.
