Pretty much what everyone else says.
If the Goal is the IT support stream.
It is all about customer support here. You need to know how to talk to a user and get the info that you need to identify the problem properly. After that you need to use that logical part of your brain to put the information together to work out what to test and what to ignore. Identifying the issue is 80% of the fix.
Certifications are good for getting attention, but on the ground experience will get you in the door more than anything else. If you can't get a starter job at a local mob, then do some volunteer work somewhere and get some knowledge and experience behind you.
Customer Service skills are your friend. Understanding how to react to an angry customer, or how to talk to a customer to get the information is key. The users are your customers, remember that when you are getting frustrated cause some Joe Bloggs doesn't know an ALT key from a mouse. Good Customer Service skills can lead you down the Service Delivery and Management paths as well.
Software Knowledge. Windows and Office, Sharepoint, 365, Adobe Acrobat, etc get some basic knowledge of these apps, specifically how to configure them etc. Configuring your own system as well, even if it is a bit you won't use, check it out and get an understanding. Learn how to respect the registry. Regedit will fix a lot of issues, it will also kill your machine. Think outside the box. Not all problems are caused by the application that is failing.
Hardware knowledge. Play at home, build your own PC etc. Reality is even though most corporates use brandname products like Dell with nbd replacement etc, there is still a lot of investigation work needing to be done to determine if it is a hardware fault or if it is software.
Mobile products. Apple. As annoying as they are, Apple are the most used brand in Corporates at the moment. You need to learn some of the weirdness and pain that Apple's particular "our way" brings.
And remember, no matter how stupid and frustrating users can get. YOUR job wouldn't exist if they weren't around. So treat them well, but don't let them walk over you.
Oh and I forgot Process and Procedure. Learn how to follow it and when it is appropriate to go around it. Learning to write it, will give you a golden look in any manager's eyes
