Life is an adventure. So prepare yourself for anything that might come your way [ It usually hurts, but hey, "No Pain No Gain" right? ].
When life pushes you down, you get back up. If you don't, just look what good THAT did for beggars / drug users.
Need any advice, don't hesitate to ask [ You might, cause getting advice from a 15-year-old isn't really wise. ] xD
