Response to failure

Yesterday I went to a bookshop to buy my Mom's birthday card. I saw a card with this quote written 'The path of success is the process of responding positively to failure'. So I bought it to keep on reminding myself the failure in studies I facing right now is the path to success if I respond positively. Anyway I realised that which topic and parts that I need to work extra on, so the actual 'A' level, I will try my best, who knows? Maybe miracle will happen. =)
