Hey Guys. :)
I hope this is okay to ask here.

Gotta few questions and hoping you all might be able to give me some insight. Bear with the possible to much info but I need some serious input here.
I am single deaf mom of five and have been out of work for ten year due to a special needs child that is now becoming stable, and a recent suicide of my partner has got me looking that maybe it is time to go back to work force.
I enjoy the tech side of things, so thought maybe I could look into a tech position at a local sprint store that I have been able to make some connections with.

I have a few months before I can do this, so what should I be studying at this point? I have been reading and reading this board as well as xda and a couple of others but not really getting the feeling that I am learning somethings that are of value, other than the tweaking and graphics. (I want more). Could I ask those of you that are working in the field what should I be directing my attention to?
I really do appreciate the input to this and as always you guys have already taught me so much - thank YOU.
