I passed my 44th birthday on flights of American Airline from Las Vegas to Beijing. It is my first time to celebrate my birthday in the sky. On the 30000 feet height, I summarized my first half of life. When facing opportunities, my give and take each time built the current me. I did made mistakes ever to miss good opportunities. But I am still struggling well. Looking forward, I may not have as many opportunities as before, so I can’t afford miss any anymore. Be confident and be alert!
