As you may have discovered, information technology (IT) does not stay the same from one day to the next. If you want a career in the IT field, you must be willing to learn every day. You must be willing to read and experiment, ask questions, and perhaps take a course or two!
Read whatever you can find that relates to your interests and goals, continue to understand yourself better every day, and know that learning is a part of working in this field.
