"Action is worry's worst enemy." -with courtesy of The Oxford Dictionary of Phrase, Saying, and Quotation-

Haha, actually I think this is more for me ba. But nevertheless find it quite helpful thus shall share. Sometimes we worry so much that we do not dare to do anything, like worrying yourself sick over a hard module. However, I think if we take some action towards the module like make notes or do practice papers, somehow or rather it makes things better isn't it? :)
