Trying to learn everything there is to know about IT?

You are definitely on the right path. You don't want to end up being a Jack of all Trades, Master of NONE sort, though. You are going to have to be generalized and proficient in many areas to some degree, but having a specialization will ensure that you are able to get a job because they will require someone with your exact knowledge. Put all that desire to learn into one field and you will certainly go far. If you have trouble deciding, use resources like knowledgebuster.com to try free practice tests in a variety of areas to see where your strengths lie and what areas you like the most. Good luck to you!
