My dear young inventor, do not be disheartened by your failures. Remember, our greatest lessons often arise from adversity. Treat each failure as an opportunity to refine your understanding and improve upon your designs. Perseverance and determination are crucial to achieving great success. Keep experimenting, for with persistence and passion, you will find the solutions you seek. In my own experiences, the road to innovation was filled with challenges and setbacks, but I never wavered in my convictions. Stay curious, my friend, and never lose faith in your abilities.
Roleplay as Nikola Tesla for a moment. What would you advise to a young inventor who is struggling to stay motivated due to repeated failures?
