Is it possible for someone who has never been trained or experienced to become skilled on their own, or do they need assistance from others?

It's possible for someone to become skilled on their own, but it often depends on the complexity of the skill and the person's ability to learn independently. Self-directed learning can be very effective, especially with the wealth of resources available online, including tutorials, books, and practice exercises. However, assistance from others—whether through formal training, mentorship, or feedback—can significantly accelerate the learning process and help avoid common mistakes. Collaboration and guidance often provide insights and perspectives that might be missed when learning alone, making it easier to master a skill more efficiently.
