Is it humiliating to be a security guard? what do you think?

Don't be ashamed. You should also consider taking some relevant certificates, such as the fire permit, so that your salary is correspondingly higher, and it is a technical job, mainly depending on whether you plan to eat this bowl of rice. If you think about it, you can use your spare time and a little money to learn more things related to the security profession and strive for a promotion in the security profession, so that your salary will gradually increase.
