If you run out of a clear and established trail, go back. That means if you're walking down a trail and suddenly it blends in with the woods, you turn around. If you feel a bit cold or start shivering, turn around. Thinking that you can hold out is great, but the further you push the farther you need to trek back.
You will need good insulation. You will need a nice, well-insulated jacket. Ski jackets are great for this. You will need head protection. You will want face protection. If there is snow, you will need good footwear and eye protection. In the snow, sunlight bounces off it and will blind you. The wind will freeze your face and you will regret not having something on you.
You will want to know what predators are in the area you're hiking in. You will always want a reliable fire starting option that you know how to use. You will always want a good knife. You will always want a container filled with water.
There is no shame in holding off or in walking an especially short hike. There is no shame in doing laps around a park instead of going on a winter hike. Dig into the trove of knowledge available to you with the internet, and figure things out. Don't fall for people saying you need stupidly expensive shit.
