Predestined?

How much of what I do in daily life was I predestined to do and what stuff i free will (if anything)? Is the reason I turned up to Bible study this morning because God had predestined me to be there this particular week? Or was it because by my free will I chose to make the effort to go because I know reading and studying the Bible is how God speaks to me?
Just a discussion that came up at Bible study that has got me thinking. Feel free to comment with your thoughts.
