Are you running on easy, normal or hard? You may want to try for an easier level before you get a better feel for things.

Don't bother with spirituality until later. Unless it really creeps you to see the skeleton in the village center.

Also, the lagoon and garden can wait until you are farther along in the game. And even the first Hut.

Put 1 or 2 villagers on foraging or farming the crops and all the rest on research. But if your researchers get weak, trade off jobs with the farmers for a wile.

I usually try for level 2 science as soon as I can. That increases the number of tech points that each researcher earns, and therefore a shorter wait for level 3 farming!
