For one thing, you do not possess a natural gift for a certain job, because targeted natural gifts don't exist. (Sorry, Warren.) You are not a born CEO or investor or chess grandmaster. You will achieve greatness only through an enormous amount of hard work over many years. And not just any hard work, but work of a particular type that's demanding and painful.
Well, that's a cheery thought for Monday morning. Demanding and painful work ahead! Actually, it can be cheery. It means if you want success you can achieve it, despite your lack of natural talent.
Of coure, I don't know how the author can state that "targeted natural gifts" don't exist. Of course they do. Some people are born being able to carry a tune and some are not. Granted, even the natural singer needs to practice, practice, practice in order to be successful. I, for instance, love public speaking. (I know, I know, I'm a complete whack.) That's definitely an inborn trait.
But, if I wanted to make a living at it, I'd definitely have to develop that talent.
So, read the whole article and get busy doing painful practice.
