Good education can lead to a good and stability career
I think a sentence this obvious has no place in your essay. An obvious sentence makes the reader not want to pay attention.
After my bachelor's degree in Business
administration Administration, I worked in an multinational company---This is the only meaningful part of the first paragraph. I think the rest should be cut.
The first reason for me to pursue MBA program is that earning an MBA degree will prepare me for management-level positions in the company.
Too obvious. I think this goes without saying. I think this is not a good use of a sentence. I know it is a true statement, but the essay can only be powerful if you focus on creating a kind of experience for the reader.
as well as a salary that has a potential to increase from MBA degree. ---again, too obvious.
The point is not to tell them your practical reasons but instead to tell them something you feel strongly about. You might feel a spiritual calling to do socially responsible business and improve employees' lives, or you might feel strongly about providing a great life for your family. You might feel strongly about improving the country's economy through good business. Express an original passion at the start of the essay, and let it inspire your writing.
What makes you most emotional? Start writing from there. :-)
