I generally try to get as close to daily building as possible because daily building is the quickest growth you can get. Here's what I've been testing:
Day 1: Pay bills, swap to happiness, collect taxes
Day 2: collect taxes, swap to lcs
Day 3: collect taxes (still profitable for my, smaller nation; it's only a 500k reduction), pay bills
Day 4: pay bills
Day 5: pay bills
Day 6: Pay bills, swap to happiness, buy infra, collect taxes
Day 7: Day 2
