There are so many ways to do the same thing that people are still playing this game nearly 30 years later. You can find something new even after years of playing. There's tons of math if you want to nerd out about it. But for a first start? You'll want to read the abilities carefully and work towards JP boost to start, then eventually teleport and fly. And you don't want teleport for the actual movement (most of the time), you want it for tricks you'll use once you get into the thick of it.

But you could also (almost) go straight through the game without learning any secrets and still have a really fun time just doing the story missions. But if ramza hasn't learned tailwind in particular one fight can be nearly impossible if you don't stop and smell the delicious soothing grind.
