"You will know me well enough and soon enough, depending on a divers range of variables" (Zusak 4).
Every day is just a fleeting moment. You will never know when your last day will be, when Death comes to claim you. This quote explains it perfectly, no matter how hard you try you can not escape Death, it will still come for you. So, instead of fearing death you should live every day to the fullest. Then, when it is time to go you should meet Death as an old friend and let him take you to the next life. For no matter when you leave, you should have no regrets and you should let Death separate your soul from your body.
