Need a general advice

I am 22 years old, completed my graduation and have started on the path of preparing for government jobs. Even though I am preparing for banking sector as a whole plus nabard currently, sometimes nabard seems like such a big mountain peak to climb. I am an agriculture graduate and since the day I learnt about it, my goal has been to join NABARD as the grade a manager. So much so that I am not interested in other regulatory bodies at all and my sole goal is being able to work in Nabard as i am just fascinated by the concept of being able to work the rural population.

Now some people have criticised me and eventually have made me doubt myself that right after graduation there is no way i can get into NABARD. There are very less seats and no way you will be able to get into this. It's very difficult, and people who do masters, or are already working are the ones that NABARD prefers anyways as a candidate.

Now this is my question to the people who are experienced in this field, consider me your younger brother and give some insight, someone who is familiar with this scenario and if you can give some advice, is it possible first of all? Or is it true that for a fresher with no prior experience it's impossible.

I am preparing for it since January, i am trying to give my all. Even though I am also side by side preparing for QRE for banking exams because I have to get atleast one job by the end of this year and I can't pin all my hopes on nabard due to the limited number of seats. Please i would appreciate any insight from you guys. I am new to all this and i really need some guidance.

Somedays I am confident that if I give my all i can do it, and other days I start to doubt myself more, that the competition is too much how will I ever be able to get into it
