I disagree, I think you're efforts say otherwise. They're the stepping stones towards your growth. Even if you make a mistake you have to look at it as a chance to evolve and perfect your weaknesses and turn them into strengths.
Congrats, @Turi. You're probably the person on PerC that people love to hate... but personally, I enjoy someone who brings up so many new questions and perspectives, always putting new ideas out there.
