Mythic GME is a big complex tool. It's not just an oracle. It has spark words and lists for tracking goals and characters, not to mention the variations. It's all to emulate a GM. You may be looking for a more simplified system like One-Page Mythic GME. Or just a simple oracle like Recluse.
Mythic is great but it's not the one solution. If you bounce off it, don't let it discourage you. You have to find a system that works for you.
Good luck on your soloing.
