Bullshit. Do you believe that there will be air traffic control in this universe with hundreds of billions of galaxies and hundreds of billions of stars in each galaxy? Other planets may have 500 days or 1000 days a year. If fortune telling is true, what should people on other planets do according to our calculations or others' calculations? Only by working hard can they succeed.
