Black Mage Help

[Criscrisis]

Ok so I'm new to FFARR and I just unlocked my black Mage. I want to make macros a set for casting fire and a set for casting blizzard spells because I feel like it'll help me pay more attention to what's going on around me. Because right now all I can do is watch my hotbar and I miss out on everything around me. So I was wondering if someone could help me by making macros for it. I don't really understand how macros work. So if anyone has the time and wants to help I'd really appreciate it. Thank you.
