Basically just explore the world and look for content. It isn't supposed to be a "grindable" thing. However, unless this exploit has been fixed in the last year I played the game:How on earth are you supposed to grind Bravery?
So there's this scene you can get with the black girl where you buy a bottle of wine and end up in a pillow fight and kiss or something. That would give bravery every time you repeated the scene. There's something else you need to do to progress her story further but as long as you don't do that, it's basically 1 bravery point per bottle of wine (which are, admittedly, expensive).
Yeah. So if you go into town via the bus depot you can find a casino that will give you a lot more money than the ice cream parlor. Also, once you have the laptop, you can take writing gigs that give a fair bit of money.Money is a huge issue
