Suggest a book for 21 yrs old guy

So here i am , i am great time book reader , i started reading books from second year of college , and right now third year is about to end and placements are going to begin
and i am from a tier 3 college and i am a music producer too
well that was about me

There might be some more , i dont remember actually
Currently i am also listening to astavakra mahageeta , as you can see from my book list , i am quite interested in spirituality but i am not closed to reading books only of spirituality
i wanna explore different perspectives in life
