I always had hundreds of thousands of exp from questing.
I was questing more than your average hermit (cause I like questing), but you should still be able to get enough exp from a few quests.
Also EXP events reset every 2-3 days. If you want to force-trigger EXP events, try to go for something you haven't gotten recently (last 10 exp events you got so far).
Some people also create an area where they can try to do multiple exp events (like standing under a willow tree and interacting with it, planting a tree, lifting a table, sitting down to eat at a table, kissing under a mistle toe, etc.)

If you're a hunter and go out often looking for animals, you'll always pass by localized resources and animals, so it should be easy.
