Are you askinng me if I'm not prepared to be successful?

No!!! On the contrary.

Failure is a big part of success.

Going through the motions - doing new things - stepping out of our comfort zone means that things may not always go to plan. There are risks to be taken that might not pay off... at least the first time. 

The key is being prepared to fail - but learning from the failure. All of our best lessons come from those failures.
