just some fun things i imagined:
-if he becomes a merchant, he would eventually have to try stopping the economic corruption within the continent.
-if he becomes a healer/priest, he would've to fight against the dark side of the main church.
-if he becomes a normal villager/farmer, he would probably have to find out the cause of eternal drought and solve the predicament of the lack of food within kingdoms.

I was hoping he aim to become a merchant. I mean he already a hero in his past life. (Fight monster and demon)
Aiming a merchant is more reasonable if wanna have a normal life....
Then he become so wealth muahahahha....
