I would recommend becoming a network designer because you don't repeat the same tasks day in and day out. You are always faced with a problem and every time there is a new outcome, it is a great learning experience. I would definelty redo this career if I had to, it is fun and it pays great!
The dialog box for selection of careers to review is a bit short in the Computer / IT Field. Although I chose "Network Designers" my career is that of a Network Engineer. I design, implement, troubleshoot and maintain computer networks and telephony systems for mid to large size businesses. I'm currently a salaried employee of a VAR / Consulting firm.
I do not have a college degree but do have my Cisco Certified Network Engineer (CCNE), Microsoft Certified Systems Engineer (MCSE) and my Sun Certified Systems Administrator (for Solaris 9).
The main pro's of my chosen career are salary and benefits. The IT field allows for very high incomes for people that carry some specific certifications. In many cases an prospective employee with IT certifications may make more than the average bachelors degree holder. I currently reside in an area of New York with a below average Cost of Living. Even with the low cost of living I receive a salary of $49,560 per year plus benefits. My benefits include health, dental and vision insurance as well as company vehicle and gym membership.
The con's of the IT field. For the most part the work is very impersonal. You deal with computers and technology on a regular basis but usually have very little human interaction. IT staff in my opinion is a very under-appreciated department in most companies.
Honestly, if given the chance to go back and make the decision over again I probably would choose a field that allowed for more personal interaction with clients and co-workers although that's simply personal preference.
