Networking is a great field. Over the years it has given my a lot of challenges and rewarding work. What ever you do, be good at what you choose…..this means taking pride in your work, thinking things through, and keeping up to date. It is so very easy to fal behind, and once you do, it is difficult to catch up. One suggestion I can make over and above all the others is read, read, read…..just because you are finished school it doesn’t mean you are finished with the homework. I have seen a lot of people do very poorly because they don’t keep up and expand their knowledge base.
You might also want to take a look at the Security field. Lots of work to be done and it is growing like crazy.
Best of luck to you.
