It is not a slogan. It is CALL TO ACTION.
Who can make your actions strong?
Do things for yourself. You cannot know what other people want. You cannot know what your horse wants. Doing actions for others makes your actions weak.
“Am I doing right?”
How do you want to judge it?
“Is everyone happy?”
How do you want to know?
Do not replace yourself with the imagination of right and wrong.
You are REAL. What you feel is the Reality.
