Breathe in. Breathe out.

Take a deep breath in and a deep breath out.

I'm not supposed to be visiting this site nor replying to the dozen threads that need replying to, but having come home, I feel like creating a blog post and here I am doing exactly that. During this fun filled exam season, I think about strange things. I do a lot of over-thinking and over-analysing. 

I have strange ideas whizzing around in my head too and i realised something. When i'm revising, i'm revising for an exam, i'm learning for the short term. I'm not revising for the long term and neither am i revising for life. For me, doing such a thing doesn't sound like a great idea.
