The key to success lies in hard work, perseverance and continuous learning. I've never really seen anyone succeed any other way. On the other hand, good training is no less important. It's crucial, in fact, because it creates neural connections that accelerate future learning and/or creative processes.
Thank you for this well-written reminder!
You summed it up well. All those ingredients are needed if you want to succeed. Too bad many can't see that.
