Although my salary is gradually increasing every year, the prices of commodities are also increasing. My current salary is enough for my daily life, and I can still invest 10% of it. I found out through chatting with my friends that many people's wages are just enough to support their families. If you want to be rich, you need to do another job. Everyone has their own way of life. I choose to invest my money, and my friends choose to travel with their own money. This is a good way of life.
