This is interesting, good topic!

I believe that we've all got predetermined lessons to be learnt, which are based on our past existence/s. I don't think there are specific events planned in our life (but thats the scientific side of me thinking about all the variables and my mind boggles at the thought of every variable or 'random event' being predetermed).

Anyway, I think we're all got lessons that we need to learn, and that our self-determination and choices are the factors with influence how we are given/learn these lessons. I also think that theres no planned outcome. If we don't learn a 'lesson' from on event we have another go (either in this life or the next).

Which, in the end, leads to the learning of all lifes lessons, and holding all knowledge (which is Buddhism is enlightenment) which leads to existence in Nirvana (the end of Samsara - moving from one life to the next). (Of course, with karma influences as well, but thats another topic altogether).
