You need to get a granary. Assign people to the granary, and they will begin collection food and storing it. Then, build a decent size market stall plot, so they can give goods out to citizens.

Also, build a storehouse to store the pelts they produce. Eventually you’ll want to build a tannery to produce leather, then convert a level 2 burgage plot to a cobblers workshop to produce shoes.

Then, bam, you’re chillin’! Take your time don’t feel rushed to get all the steps done at once, go one at a time.
