If destiny designed a master plan which defines everything that is to happen, isn't it useless, for example, to go a Geocaching event? If I am suffering withdrawal symptoms from caching and it is my destiny to go caching, then I will regain a caching balance whether I go caching or not. If it is my destiny to not go caching, then going to an event cache can't help me.
But as this only an example of a paradox and can you choose to or not to attend.
We shall see.
