We Human beings make some mistakes every day every night. Essentially speaking, it is fate for us to do so. Because no human is perfect.
What I'd like you to think of is that I'd like you to be courageous and constructive enough to take action in your daily life.
How you take action today changes the quality and direction of tomorrow. What you need is action you take, especially the "quality" of action you take.
All human beings learn important matters by inches through making mistakes in their daily life.
As the proverb runs, "Experience is the mother of wisdom." I'd like you to passionately experience various matters every day every night and develop your individuality beautifully.
