修練か後悔か

“We must all suffer from one of two pains: 

the pain of discipline or the pain of regret. 

The difference is discipline weighs ounces while regret weighs tons.”

 Jim Rohn quotes (American Speaker and Author. He is famous for motivational audio programs for Business and Life. )

イノベーションは、修練。
Needless to say, innovation is discipline.
