There is more competition in fashion design than it is in a career, but if you want to increase your ability to reach the top of success in your own field, you will have to enhance your skills.
If we talk about the MBA then the first important thing is that you are already paying a loan of your gradation, in such a situation, another loan will increase your financial burden, but if you want to complete one loan first then taking another loan, then it would make more sense. Meanwhile, if you want, you can prepare for the entrance exam related to the MBA so that you can get the best college. Nowadays many institutes and colleges offer MBA but you must score good marks in the entrance exam for the best college.
As you said that you have much experience working in the private sector but you do not feel a good working environment here and if you are interested in a government job, then, first of all, I would like to tell you that any job has its advantages and disadvantages. It Depends on how you accept it. My advice is that you should keep your professional life separate.
As far as the matter of government job is concerned, you will have to prepare a very hard and serious study for it. If you want, you can prepare it with your job as well, for this, first, you have to set your mind to prepare for which exam or for which post, then prepare the entire preparation strategy for it. You can also take the help of YouTube channels if you want.
Don't just think that any government job is needed, because every exam has its own syllabus and has its own separate preparation, so first, you decide which of the government positions to choose from, and then decide for preparation accordingly.
In the end, I will say that whatever decision you take, either an MBA or a government job, but do not hurry, and don't leave your current job because you are already financially responsible for giving a loan of your education, so it is important to maintain your fixed income.
