Live by the day and harbour no regrets
As people age they become kinder to themselves and less critical of themselves.
They become their own friend. Many dear people leave this world too soon, before they understood the great freedom that comes with maturing.
Whose business is it if they choose to read or play on their computer until 4am? Or sleep until noon?
Perhaps they're sometimes forgetful. But, there again, some of life is just as well forgotten. And they will eventually remember the important things. Don't waste time lamenting what could have been or worrying about what will be.
The body may age, but our minds can stay in eternal spring.
