I am of the opinion that for one to be able to realize his/her purpose in life, he/she must possess intuitive ability to keenly listen to his/her inner voice, especially if, it entails the use of one's creative faculty. I must admit that, this process of finding one's purpose in life is not a walk in the park, as it requires deliberate self-driven soul searching process.
Personally, I was able to discover my creative writing skills at a very tender age, when I was still in secondary school. And I must admit that, it took me conscious efforts before I was able to discover that hidden treasure embedded within my soul. It was a challenging feat that needed my utmost focus, determination, and persistency. Additionally, there was also a bit of consistency in the earnest striving to discover the gift I was blessed with, and this was propelled by the will of self-discovery spirit.
Furthermore, after under going the discovery process of honing my skill, then came the task of unravelling the true definition of the skill, through repetitive practicing in order for it to be properly polished.
Lastly, if one's talent or gift is not proper polished, the discovery of it would be for nothing, because it would be like a gold mine discovered that is left untapped.
