"Because once you are down, the only way to go is up!"
You are absolutely right, my friend. The only way is UP. And, the only time it is ok to stay down is when you have not figured out how to get up jet. But, even figuring out is way better standing up. You have a way better vision in front of you. :)
Failure is just a roadmap to success!! :)
It's a part of journey, failing to learn like falling to fly!
