I want my life to be fixed, only need 3 Cr.

I am a working professional, and of late, I am just wondering, moreover, calculated it all, I only need 3 cr in my life, and everything, legit everything will be sorted, and I can live a wonderful & peaceful life.

Now I know that 3 cr is not even close to what people might need in their life, per se, but I am a simple man; I know what I need and how I can manage everything.

Tell me, how can I make this much money, or is there an alternate way to do so? I might be naive to talk about all this, but that's just what I need at this point.
