I don't remember a case that I thought a special number was lucky for me. In particular, the number 7 which is a favorite to me, is the same. Among the soccer players, players who play with back number 7 are particularly interested. Son Heung-min, a Korean soccer player who plays in the England Premier League, and Ronaldo of Portugal have seven back numbers. I cheer the players without realizing it. Is this the magic that number 7 has? But actually I'm living in the strong luck of number seven every day. Saturday, the 7th of the week, gives me the energy to live the week hard. After all, I can have a sweet break on Saturday. Isn't this the power that number 7 has?
