Tiny Tiny Fonts: How do I customize my own GUI?

Greetings!

This is my first day with Unity and I’ve decided it will be the program I’m going with for making my first MMORPG. There is one small problem:

I can’t see half the fonts. I’m squinting to see things like “create” and folder names in Assets. “Inspector” was almost completely illegible. I understand most users won’t have this problem but my eye sight isn’t that great. How can I make the font sizes bigger? I’ve also seen something called “skins” and wonder if those might help or how to make my own.

Custom skins are for your own games; the font size in the Unity editor can’t be changed.
