Settings the defaults should be seen as a safety feature, in case your turn gets lost or anything like that. If you're going on holiday or are away for more than two or three days you're much better off getting someone else to act as proxy.

Don't worry too much about not knowing exactly what to do. There is relatively little to actually do in the first few turns, and learning about how things work is part of the fun of the game. Compare it to getting life experience in Real Life (tm).
