What was it like in Inca society?

This is a very broad question.  I would recommend that you
follow the link that I have provided below.  It will give you a great deal of
information on the daily lives of people in the Inca
Empire.

Of course, the vast majority of the people who made
up Inca society were what we might call lower class people who had very hard lives. 
Basically, their lives were made up of hard work that they had to do all day, almost
every day of the year.  For example, the common people in the Inca Empire were expected
to do work for the government and for the temples of their religion.  They had to finish
this work before they could do work for themselves.

The
Inca commoners did have some time off to have fun.  But it was mostly state-sponsored
fun.  The government put on festivals and things like that and people had to go to them.
Scholars argue that these were meant to help make the people be less unhappy about all
the work they had to do.

Again, you should follow the link
because it has a great deal of useful information about all aspects of Inca
culture.
