ARR and Beyond!

[Raldo]

You should definitely try whatever jobs interest you, but I generally advocate getting at least one job to cap (unless you start to dislike your current job) before bothering with others, and working on plowing through the main story so when someone asks "Hey, want to do XYZ?" you aren't forced to say "Sorry, I don't have access to that content/zone/whatever" (which has happened quite often in my FC recently with those who drag their feet on the main story...).

Aside from that, it's worth noting that important quests (quest chains that unlock various content) are somewhat blue and marked with a little + sign on the ! marker. You should definitely prioritize those over other sidequests.

Hopefully this image displaying the !+ sign works...
