Sticks & stones can hurt you & knives can kill! Just remember, leave the knife in, overcome the pain, then keep the spirit piercing weapon as your motivator to prove to those that choose to play with knives...they..are the ones that really get hurt.
There is no such thing as losing or failure. If I am not "successful," at something I consider it a learning experience. Taking every opportunity to learn from a mistake is a great way to develop as a person.
