Getting tired of them shaking their head at you at complicated tasks? Waiting for improvements?
I find this has helped....
Get the builders to the beach. If they keep shaking their head, keep picking them up and plopping them back down on the wood. They quickly level up to adept builder. Then run them over to the hut.
I find this works faster to train, instead of waiting for them to travel all the way left or right with wood or rocks to find out they shake their head no. Do the beach until they are adept builders.
Same thing with farming and medical. Pick them up and plop them down each time they say no to things.
I find later in the game, get them to do the berries to train, instead of waiting on the garden or fishing. It's quicker.
Just remember also, pick them up once they stand up from a job done and whoosh them across the screen. Exspecially when removing the rocks. Some of those people just meander over, so I pick them up and whoosh them faster.

Try and get all your farming done. Then it's easy sailing from there. Just have your little ones run around getting mushrooms and all your players except 1 to research.
I think orange mushrooms are worth 30 food????

Then get your health, cause they die fast if not resaearched.
I still have no idea what the fertility study is, because I got triplets with the first try. Dang! I did Fertility and construction last.

Mushrooms are worth more with the mushroom trick. I have kept my villagers alive until the crops came in with that trick.

Third level Medicine is my last buy, I go food to 3, construction to 2, science to 2, and fertility to 3. Then I worry about the rest.

Mushroom Trick? Please explain cuz I'm really really low on food and I don't want them to die (again)!!!
