Tips for living in Korea

Hello, I have been living in Korea for over a year and would like to know how people live their day to day lives. I am an alumni, but my friends say that they are bored with eating out at home. In Korea, we often use convenience stores and 다이소. We also often use delivery services. For transportation, it is convenient to use T-money, but sometimes we get lost. Please share some useful tips from your own experience.
