Punch
Close your fist, pull back and punch. Every blow needs a fresh pull-back, so holding a fist against something does nothing. Chips fly to show a blow counted. Harder punches break more.
Grass fibre
Dig grass and you get fibre. It goes into your first tools, the Cooking stick and the Bedroll and sleeping, and it starts a Campfire.
Pick up what falls
Walk close to loose wood, stone and ore and it flies into your pack, as long as there is room. Fruit you pluck with a grip, see Fruit and planting. Hunger weakens your blows, see Food and eating.
