I am a security guard now. What do I want to be inspired by? ..

You can do some small business part-time, hehe. For example, I used to be bored at work, so I took tea from home to sell, which not only earned a little money, but also fully justified my time.

Another word is study and exercise. Besides selling tea, I go running in the morning and evening, and then I go to learn calligraphy after dinner. It depends on your hobby.

In short, it is ok to earn more living expenses, develop your hobbies or lay a foundation for your later life.
