A little late on this, but their is more then one way to so called success. If I practiced 10,000 hours on a viloen I would be good, but never great. If I was born with talent and did not prcatice I may be good, but not great. If I had talent and practiced, but had no great formal instruction I may be good, but not great. If I had all three I would be great. And the same goes for my spelling and grammer.
