The way is:
1. "Naked" - you only have basic clothes and some food, no valuable items, or take a challenge to rid all of your inventory:
Make torches by cutting branches from tree, then torches. A torch is very cheap (value <1) and can only trade for a piece of low-nutrition meat, or turnips, a cord, or worse. But this is the only way you can made money from nothing. Then you trade it for some tools like fishing rod (4 for normal quality), or juniper bow, and proceed to step 2.
2. Fine - you have a knife, or fishing equipments. Make simple woodcrafts (clubs/staves) which is slightly better than torches, or fish large ones like pike, burbots and trouts, and optionally cook them. There you get more money, and proceed to step 3.
3. Good - you have a valuable item, like a piece of clothes you do not need, a spear (value 344), or something else, like a culture item (not suitable for crafting) or jewelry. You just go and pick arrows, or other currency to start with, and trade them to a handaxe or better - or luckily, you have something good, like a item more than value 200, you can directly pick an axe, and some food/arrows.
