How to control your own destiny

Once I visited a friend with a successful career and chatted about fate. I asked: Is there a fate in this world? He said: Of course. I asked again: What is fate? Since destiny takes a hand, what's the use of struggle? He didn't answer my question directly, but just smiled and grabbed my left hand, saying that it would be better to read my palm first and tell my fortune. After telling me a life line, a love line, a career line and so on, suddenly he said to me, reach out and do an action like me. His action is to raise his left hand and slowly clench his fist. Finally, he asked. My puzzled answer: Hold on tight. He asked: Where are those fate line? I answered mechanically: in my palm. He asked again: Excuse me, where is fate? I was shocked and suddenly realized that my destiny was in my own hands! He went on calmly: No matter what others tell you, no matter how the fortune teller calculates it for you, remember that your destiny is in your own hands, not others' mouths! This is destiny. Of course, if you look at your fist again, you will find that there is still a part of your lifeline outside and you haven't caught it. What enlightenment can it give us? Most of our destiny is in our own hands, but some of it is in the hands of "Heaven". Throughout the ages, the meaning of "struggle" is to exchange your life's efforts for that part of "destiny" in the hands of "Heaven". I listened quietly. For a long time, I only felt that my heart was like a clear spring, flowing through my fate in my own hands, not in the mouths of others!
