Skills are different from abilities, you have to work at them to achieve anything. Someone (Usain Bolt) may be born with the ability to run really fast, but no one ever just sat in front of a keyboard and wrote a critically acclaimed book. To be skilled in something you have to work at your craft until it appears as though it is an ability.
Look at The Beatles, the fact they appeared on the music scene with this amazing ability to write hit after hit ignores the fact that they spent many hard years honing their skills in bars in Hamburg and Liverpool.
