No problem! That's how I started getting into repairing phones as a hobby; I studied iFixit guides and YouTube tear downs almost ceremoniously just out of curiosity and passion for learning how my iPhone is put together... Well one day, my friend at work had a broken screen on her 4s, and I offered to fix it for her. Turns out, after I did a good job at it (beginners luck), people around work caught wind of what I was doing, word spread, and the rest is history.
I think if you take it slow and begin with the easy stuff, find an opportunity and don't screw it up...you might find yourself fixing phones one day. Just for fun.

Best way to know all about the device you use every day...what to do/not do with em, know just how durable/fragile which parts are, etc. Good luck! Sent from my iPad.
