I am just curious as to what I am supposed to be doing. Which tech level should I buy next? Building or spirituality or some other one. I am just stuck.

I already read some spoilers so I am dreading the arrival of the gc, but am aware that it will solve some of the puzzles for me. I don't want to ruin the whole game for myself by getting blatent directions on what to do but I am at a point where thet aren't doing anything but laundry, excercising and dancing.

Ok, so if you can just tell me the next step to get me rolling again that would be great!
TIA!!!
