How am I different now that I've learned about Hardware Trouble Shooting???

I think that I'm a lot different because at first i didn't know how to work Trouble Shooting....but now i do. I none of my friends back at home or at school know how to work on the hardware trouble shooting.....at first i didn't think that it was going to be fun because the teacher was telling us to go to all of this different things and saying some things that i really didn't understand.But after we had got go going I liked it more and more.....
