Everything you do is worth it no matter if the outcome is not what you hoped it would be. Take it like It is and run with it till the wings fall off!!
Do what you can as long as you can till that risk becomes an adventure with a story to tell. You will never know what fun is until that one moment when you think back of what you did and everyone just listens to your stories.
Fun times are always enjoyed in conversation which makes you less boring so go for it and take that leap off that cliff or plane and FLY!
