Don't listen to him lol
First you should do the Knight quest to get some basic gear.

To improve this equipment you should add cards to it (I recommend Silver MVP cards for starting, they are sold in player shops)
The money for those can be quickly earned by killing some Mi Gao in Louang fields (Mi Gao drop the item gold which sells for 100 000 Zeny each)
The best way to start making real money is doing the Forsaken Dungeon quest so you can start farming some Berry tix

In the dungeon there are mobs which drop the Yggdrasil Berry item (use @ali 607 to pick them up automatically)
You can convert 100 berries into one berry ticket at the ticket npc (@go 25 then go up the stairs, the npc is at the left)
You can also join the events if you like, but that's more like gambling so you can fall pretty low trying to earn quick money.
You can also do the following quests to first gear up a bit and then redo the quests to sell the finished product to players
L.Weapon quest
L.Gaunlet quest
L.Zodiac quest
L.Avian quest
I also recommend doing the Avian and Zodiac quests early so you can put more cards in your headgears. You can put Silver Kiel cards in all headgear slots to make farming faster.
