At the beginning, the Daily Mission is like free gifts from AC. But the bar gets higher and higher. Yesterday, my mission was to complete 30 flights and visit 110 commercial buildings. Now I have to keep one or two hangers for the training flights which limits the number of flights to other destination. I believe the bar will get even higher when the level reaches 40. I don't know if I should continue or it is time to give up. Any opinion?
