There are many ways to better your citizen in this game! One idea is to go in prison. It may sound dumb, but you can get free room and board, and work for companies for less, giving them better leeway for their future. I wouldn't reccomend running for mayor because it's just not worth it. Also, try not to spend a lot of money on food because then you're nourishment goes to high, it's better to be mal-nourished than overly nourished. Also, take heed of Amboo's advice, he's an old veteran looking to help out younger players.
