Career break - will you regret more if you take it, or if you didn't? A mid-week contemplation of a perhaps different way of living

Anyone taken or thought of taking a break (or sabbatical leave) from a job?

To figure out what you want in life? What have you thought of doing/exploring? Hope to achieve? Can be because of career-wise or can also be general directive or outlook. As a crossroad that could even be a turning point in life.

To those who made the leap of faith, what did you do during the break? Any regrets? Do you think about the what-ifs, opportunity cost often?

Appreciate any sharing :)
