A Lifetime is But One; Happiness is the Most Important Thing
In a lifetime, joy is one day, and sadness is also one day. Why force yourself to be unhappy? Yes, we only have one life, a life where mistakes cannot be repeated, and broken hearts cannot heal.

Today will never come again; every second will never be revisited. Why waste our time complaining and regretting when we can cherish the present moment?

In a lifetime, we can face things calmly, and we can actively seize opportunities. When you can't accept something, when you're feeling proud, when you're resentful, or when you're trapped in pain, remember this: no matter what, you're lucky to have this lifetime.
In a lifetime, there is no afterlife. Let's start with a smile! Living a happy life is the most important thing. Having a healthy body and doing things you love in a happy state of mind, safely realizing your own value, is the greatest happiness in life.
