Idea: Explore books by ideas.

I'm used to search for books in two modes. In the 1st mode, I follow recommendations I receive from various sources (podcasts, individuals I follow, etc.). In the 2nd mode, I identify what is interesting for me right now, and search for the books that elaborate on the topics I'm currently curious about.

An idea that I propose is to create a place where one could see the essential ideas, excerpts, quotes from various books in the Tinder-like manner (or not): choose what you like right now, so the system reveals a book where this idea/quote originated from.

It's not a book summary app. The goal here is to have a possibility to dive deeper into the topics a person is currently interested in.

STRONG PERSONALITIES HAVE THEIR PRINCIPLES

I am telling you a must have trait if you want to build your personality.
You must live with your STRONG PRINCIPLES!

If you decided to not to smoke or drink, NEVER DO IT whatever the condition is.

THIS IS YOUR PRINCIPLE.

If you decided not to eat non-veg, then never do it.

YOU CAN HAVE YOUR OWN STRONG PRINCIPLES IN LIFE!

The thing that matter is to follow them no matter what the condition is!!!
