In contrast, it took about a year for each language for me to feel comfortable having a conversation in French, Turkish, or Arabic (while my Arabic has since deteriorated...)
The first time you study a language, you are not just learning the words and grammatical structures. You are learning HOW to learn a language. The second time around, you already know how to learn, so your progress is exponentially faster.
Well, it appears to me that success in entrepreneurship follows a similar trajectory. You may have exposure to related skills from family or childhood experiences that make it easier. Or you may struggle, looking at your peers, wondering why they just get it. But if you don't give up, you learn a word or a new skill here and there. And one day things just start clicking into place.
The next time you start a business, or push the original one forward with a new initiative, your progress is much quicker, and people think that you were a natural all along. Patience pays off!
