How does it feel when your salary suddenly increases a lot?

Born in 1990, a female majoring in engineering. She graduated in 2014 and came to Beijing to work in sales at a well-known Internet company. The basic salary was only over 2,000 yuan. After four months of working, her monthly income was more than 3,000 yuan plus commission. The rent of 800, plus personal expenses, there is almost nothing left! Unable to adapt to the work atmosphere, I decided to resign and have been working as a project manager in an entrepreneurial company for almost 4 years now! The basic salary during the probationary period is 4,000, and the salary after being promoted to full-time is 5,000. Because of my good performance, my salary was directly raised to 6,000 in 2015. Plus there are commissions from the project, the income is not bad, but I am really tired. I work overtime every day, always be ready to answer customer calls, and stay up all night from time to time. ! Because I am cross-professional, I don’t understand many things, so I can only study hard! At the end of 2015, my boss planned to set up a new department and asked me to lead it. However, due to insufficient consideration in all aspects and my own lack of experience, the department was disbanded within a few months. I returned to the project department to continue working, leading a bunch of projects and a group of new people. Physically and mentally exhausted! I applied for a salary increase to 7k at the beginning of 2016, and the company raised my salary to 8k in the middle of the year. Plus commissions, my monthly income is over 10,000! Internal salary adjustment at the end of 2016, to 10k! In 2017, due to his outstanding performance in all aspects and rigorous thinking, he has grown into a key employee of the company and was transferred to the product department. Since there was no commission, the basic salary was adjusted to 15k. Fortunately, he can basically go to get off work on time! Not long after, I was promoted again and was transferred to the project department as a project manager. This year I started to enrich myself and obtained the PMP certificate. In 2018, I applied for a part-time graduate degree. My basic salary was increased to 18k. I managed more than 20 people and became a middle-level person in the company. The management staff, currently pregnant and studying, are still working hard! It feels like my salary has exploded!
