I work in the financial industry and my monthly income is not bad

I work in the financial industry, and my monthly income is not bad, but because I didn't plan well, I was impulsive and consumed ahead of time, which led to relatively high financial pressure, and I couldn't make ends meet every month, so I considered taking part-time jobs.
Whenever the monthly salary is paid and the car loan and housing loan are paid off, there is not much left. Whenever this time, I am glad that I have a part-time job and have a small extra income to cope with it.
