Everything is part of your personal story... And as that story is a thing that exists as a sum of all its parts, you could say that it all has a reason or purpose. 

There are two messages that commonly come from the psychedelic experience which may seem at odds with each other: on the one hand, go with the flow... Don't fight the path you're on. On the other hand, you are the creator of your life, the master of your own destiny... Don't expect rewards without taking initiative. So which is it? I think the two opposing ideas are both vital and serve the greatest purpose when they reflect off each other, exist within each other's influence. Find the path that suits you, seek the thing that fits your personality, your needs. It can take an almighty push to get yourself on that path, but when you find it you should be able to flow with it. Every struggle that you encounter in getting there provides meaning and depth. If you engage your life fully, each and every little part will have its place.
