JRR Tolkien did not begin The Hobbit, the first of his fantasy works which he completed, until he was well into his 40's, and did not begin Lord of the Rings until he was 45 and had finished The Hobbit! And think of how immense Lord of the Rings is!
But this is far from the most extreme example!
Saint Helena, Emperor Constantine's mother, was a legendary Christian saint who is famous for going on pilgrimage to the far side of the Roman Empire to Jerusalem and finding the True Cross!
She did not even convert to Christianity until she was in her late 60's at least, after her son Constantine converted!
So never think it is too late to do something great!
Gene Roddenberry did not create Star Trek until he was in his mid-40's, and he lived to oversee six Star Trek movies and four seasons of Star Trek: The Next Generation- and to assemble the creative team of writers who would carry his legacy on so well through Star Trek: Voyager and the 9th Star Trek movie!
Never think it is too late!
God loves you!
Sincerely,
David S. Annderson
