Oh man, sounds like if you know how to use a computer and how to follow instructions from google then you're pretty much good for the job. You almost already sound overqualified. You don't need luck. LOL
Just be sure to overcome your problems with speech and you'll be fine. Join up with a Toastmaster's group or something.
minorcharacter = wise one
yeah, seems like they are looking for 1st level tech support... should be easy peasy. like minor says if it's speech/confidence that needs a little omph... toastmasters are fun. if i had more time i would join one too... it's kinda fun speaking in front of a room in a take charge kind of way, like you're some leader/ceo of a non-existent billionaire company.... totally fun.
