I can empathise with your point about failure.
Here's my story:
I spent most of my twenties working as a freelance journalist for newspapers, magazines and even a national radio station.
I slowly learnt how to avoid my mistakes, but I still struggled to learn a living out of this strange profession.
I discovered a failed creative project is tough to swallow, but it provides you with a great chance to learn more about yourself and your craft.
All you have to do is ask the right questions about what you gained and lost and then capture and apply these lessons before you begin your next work.
Fall forwards!
