Is Sacrifice important to FIRE?

While i like the concept of fire and having a goal, it seems to me that happiness is more important in life. Many would have seen the movie ZNMD, and while its important to be financially secure, its also important everyone enjoys the present. I am ok to retire a bit later but i don't wanna compromise on my enjoyment. This age/time would never return and who knows 'kal ho na ho'. Am i wrong here?

Just for context, i am 35, living by myself, have visited 6 countries, and have 1 cr net worth. Don't feel the need to marry as my lifestyle is ok.
