In it, you will run though muck, you will scale walls, break though glass, leap over hurdles, you will wade though sewage, and you will pass those that fail and cannot find a way around. You will never know what will come next, you will have to be prepared for anything. Sometimes, if you are lucky, you will find someone to run through this mess with you. Someone to hold your hand and urge you on. Someone you can count on, someone who will not care that you are covered in shit. Sometimes they will fall, and you will help them back to their feet. Sometimes you will fall, and they will be there, covered in mud and sweat and blood, holding out their hand for you. You cannot stop, you cannot waiver, this run is the only one you will get.
In the end, when you have dashed and jumped, and crawled and clawed, bled and suffered, and you can go no further, you will look back and see all that you have done, everything that you have accomplished. If you are very lucky, you will still be holding their hand. You will be able to look at them, smile, and say “I could not have done it without you, thank you.”
