Passion and Talent

While reading the book Supernatural, I spare some time to read a book recommending by my ex-colleague – “Chasing Daylight” by Eugene O’Kelly. This book is about what one shall do before too late. I cannot tell whether it is a good book yet as I am only half way through it. However in the earlier part of the book, there are a few paragraphs that put me in deep thought.

One day when I was 14, my mother, who for years had witnessed my passion for the sport, told me it was important to distinguish that from talent.
“What do you mean?” I asked.
“You may have the passion to be a great baseball player,” she said, “but not the talent.”
… She wanted me to hold onto my passion while also following a path where my talent could flower.

The whole idea struck me … I may have the passion to build the greatest web site or the best book cafe in the world; but what if I don’t have the talent to do it ?

Shall I drop the idea ? Or keep pursuing it ? Is there anything on earth that I have passion with and I have the talent to realize it ?
