I can say that so much was a waste of time when we look back, however we did it anyway. How about 2011, if you were studying in 2011 or taking classes, chances were that in 2012 you still were. If you decided its a waste of time doing what you did you would not be doing it now.
So anything we did was just an experience while traveling the path were suppose to be on. Without those things we found a "waste of time" we would not be on our path to our destiny. We are where we are for a reason.
The reason will surface now.
