I really enjoyed your story, thanks for sharing. My heart went out to you at first, feeling your pain over missing your dad, and disappointing him. Then I came to the same conclusion you did. His abandonment of you made you the talented man you are today. So in some ways, he did shape your future. But remember, the only actions you control, are your own. So put the disappointment and misery behind, add some jokes to your act, and keep on going. Good wishes to you.
