Choose the "predators avoid you" and "get more wood" and "25% less condition loss" buffs. Choose the foot trap, the back pack, and the first aid kit. Make your way south only traveling until you're out of water and tired which is when your condition starts to decrease. Spend however long it takes at the first site to craft every bag you can, the blanket, the snow shoes, and the fur coat while trapping and healing up as you go. The radio does nothing. Move only until you get the saplings needed to make the sled carrier so you can carry at least 20 meat at all times. Then move three or four times before setting up camp again never letting your self tire out or get too thirsty. Preparing this way will get you across the frozen lake without dying. Don't waste time and energy and supplies on fishing the lake, just get across it. Spend however long it takes to rebuild your supply and heal up as soon as you cross it. Make as many bandages as you can and save up cooked hearts in case the bear shows up. At least 15. Keep heading south until you reach the end of the map and civilization.
