I'm not convinced that faith and achievement are interlinked, as your thread title suggests. But put the lube away, please, I didn't need that graphic of a description of the disagreements that are sure to follow your OP - wow. 
The athlete that wins a championship or gold medal does it after many, many hours of deliberate and goal-oriented practice. Same for accomplished musicians or for you while zoning into a difficult piece unencumbered by thoughts or self-doubts or even me as I finally nail a piece I've been practicing forever on my violin.
Believing you can achieve a goal is part of the puzzle but it's not the entire picture.
