Why look forward to after 'A'?

With all the studying, I think my brain is a little fry. But thinking it through, after 'A'  means that life isn't all that simple of finishing your hwk and going out with friends. There is an even bigger meaning behind it - the fact that we are 18, so we can do whatever we want to do. So...what to do? When you first think about it, there may be SO MANY things to do - so many countless things that we were unable to do when we are studying. But then what? You can't possibly do ALL of those every single day right, so there got to be a plan. Then things become more complex. Do I want to do things that I will never get a chance to do it ever again (sounds logical right) or should I be earning money or do meaningful stuffs? It just all becomes so much more complicated that why look forward to after 'A'? True...there will be more freedom, away from the notes, away from the unpredictabliity of cambridge examiners. But there is uncertainty in the real world as well and I would say it is larger in scale.

I guess time and experience will be needed to get used this other side of life that is not school life.. No matter what we are alumnus of the school...
