Hello aspirant

IAS IPS is not about money it's about responsibility So choose this only if your very passionate about then go for it.

A Pharmacy business gives you a lot of money which will not be fixed nor certain.

So its upto you what you want to do.If you care for only money then go business but If you feel like serving your nation then go for UPSC CSE. Pharmacy business is also a great work for the society but its not like Civil Services.

Hope this helps. All the best.
