I've never made it further than that in Don't Starve either.

Valheim is much easier in that regard since, like has been mentioned, you cannot die from starvation or thirst, and even I have gone very nearly 300 days without dying once.

Once you learn the game, and as long as you're careful, it's not too difficult to avoid dying. I can't speak for others, but I know pretty much all of my deaths have been because of recklessness, not paying enough attention, or stuff like that. (Not counting deaths when I was still learning the game.)

Three basic things to keep you alive (plus obvious things like don't get hit too much or fall off cliffs):
- Keep your HP and stamina up with food
- Always be aware of what is around you; some dangers can be sneaky or sudden
- Don't overestimate yourself, or underestimate enemies or even the land itself (Very hard when starting out.)
