One First and Last attempt.

I am 35 years old individual working in a PSU. I am married, and have a 4 year old daughter.

Since my engineering college days I wanted to become IAS/IPS, but due to many different situations and wrong choices I ended up working in a PSU after graduation. Now when I have almost a very stable lifestyle where there is no presence of any worries or problem, I can see my future bright, the lifelong dream of becoming ias/ips is taking over my thoughts.

I belong to reserve catagory, so I can appear for the exam given the age relaxation. I am thinking of giving one year to preparations starting Feb 2025 and will take exams in year 2026.

What would you advise me?
