10 Types of UPSC Aspirants 

Have you binge-watched 'Aspirants' or immediately searched for Manoj Kumar Sharma after watching '12th Fail'. These art pieces portray the popularity of the UPSC examination. Approximately 10 lakh people apply for this examination every year. This implies, that tons of people choose to go through the rough and tough journey of being a UPSC aspirant, sometimes twice or thrice thinking: 

 But, not every aspirant is sincere. There could be different types of aspirants. 

So, let us talk about the different types of UPSC aspirants:

1. The architects: these are the type of aspirants who devise a strategy for everything from solving previous year papers to newspaper reading. These are the aspirants who are most likely to get the results as planning is the core moral value of a civil servant's life. 

2. The dreamers: These are the aspirants who daydream all the time. They aim for nothing less than IAS. DM is the only post they know about. The royal entry motivates them, the charm is all they want. 

 Every other aspirant: I will be making policies for the education sector, and health sector; will reprimand for violating traffic rules..blah blah blah

3. The manifesters: these are the aspirants who use affirmations, visualization, gratitude, and goal-setting to align their thoughts and actions with the desired outcome of becoming a civil servant.

4. The jugglers : These are the aspirants who prepare for UPSC along with their job or studies.

They are always struggling to strike a balance. They tend to be in FOMO. 

College-going students sometimes miss classes. Other times, they have to pull full-nighters to pass the semester. They have to choose Laxmikant over Jubin Nautiyal or Arijit Singh (artists of Star Night). 

Office-going aspirants have to sacrifice their Fridays, club nights and office parties.

5. The parrots: These are the aspirants who are always lost in the ocean of topper's talk/ interviews/ Bhaiya's advice. They inhale topper's talk and exhale editorials. They listen to every topper's talk and apply everything that everyone is saying. They could go so far that they use the same pen that was used by their favorite topper. 

6. The collectors (pun intended): these are the aspirants who become collectors before joining the service in real life. The only difference is they collect books, magazines, coaching notes, etc instead of revenue. This can even go to the extreme of collecting refills of pens they used in practicing answer writing.

7. The Lukewarms: These are the aspirants who get excited by watching Ankur Warikoo or Deepak Rawat or shorts of IAS Srushti Jayant Deshmukh on duty and then they study for 8-10 hours a day(sometimes 12-16 hours). 

But this motivation is as frail as the touch-me-not plant. Which droops when touched and re-open a few minutes later(just like a UPSC aspirant getting back to schedule after watching another motivational video/speech)

8. The underminers: These are the ones who undermine themselves. They are worried and are always in self-doubt. While sitting on the study table with a stack of books, instead of studying, they get immersed in questions like Do I have what it takes? Will I ever be able to accomplish that? and so on.

9. The perfectionist: These are the aspirants who wait to craft a perfect booklist, for the perfect time, for the perfect study schedule, etc

10. The procrastinators:

These are the aspirants who procrastinate till the notification comes out, then they procrastinate till the books are delivered at home, the lectures are posted, the notes are provided and the list of rationalizing excuses goes long.

With this, we come to an end. We hope you enjoyed it. If you are a UPSC aspirant, we hope it has given you a chance to introspect and reflect. We salute your courage and wish you luck. 

If you are not a UPSC aspirant, you must check our future blogs to get assistance with your career.
