Can someone coach me how to teach me to mid properly

I have been playing league for 2 years now and I have started to mid for my team and I would like to get alot better at it. I was hoping that their is a good person out their that could give me a hand and teach me how to become a better mid player. I am in gold 5 right now and would like to hit a higher rank this season than last season. I would appreciate this greatly if someone could help me out. I am free most days and except Sundays, and Wednesdays but the rest of the week I'm free after 8pm.
