Directionless at 60

Hi! I'm a level 60 I/L wizard which is the highest level I've ever gotten to. I returned to maplelegends after like a couple years, started this character, and got to 60 in just a few weeks (while also trying other characters and classes). I used the wonderful "exact guide for 1-35 in under 6 hours" post as a way of trying lots of things, but it seems like quests that REALLY help in leveling become very sparse after about 40, so I've kinda just been poking around, grinding at random spots, and eventually found the ghost ship to be the fastest, getting about 4 levels in a couple hours with the help of a GM buff and a random cleric I ran into. I wanna know if there's more quests or anything I'm missing that might help me along or give me some sense of direction, because I'm worried I'll just fall off and lose interest again if the expected/best option is just buying TONS of MP potions and going in circles fighting slimeys for the next 10+ levels I'd love to get to the next job since I've never seen any of that, even when I played in 2007
