The most important thing is today's heart
Why do you want to lose your present mood for painful regrets, and why do you want to live in fear for inexplicable worries?
The past is gone forever, and it's no use regretting.
The future is still out of reach, no matter how worried you are, you will be sad.
Today's thoughts, today's events, and today's people are all real and feel good.
Of course, it is wise to sum up past experience and guard against future risks.
Yesterday has passed, but tomorrow hasn't come yet. Today is real.
