My condolences on your incredible loss,
Do not be afraid of failing, that means that your not taking chances and to be the best we all must push ourselves to our limits.
Failing comes with wanting to better yourself, of course we try to keep those to a minimum!
What makes a man a man, is not his burdens or responsibilities that he has put upon himself but the capability of always winding up on top through rough seas and bad weather.
I don't know you but it seems as if your father gave you all the tools to be the best!
Godspeed!
