Beautiful past

Past is gone past

It comes back not

Present becomes past

Faster than one's thought

One who thinks not of time past

Newness he may create

But with the same faults

Time flies and die is soon cast

Make past beautiful

And live present to the full

Past serves as a beacon to those

Who think and are careful

One's childhood is when past

Adulthood is also gone

And responsibilities are burden too heavy

He then remembers the sweet past

No need to live in the past

When life has already seen is a lot

Plan, think and do what you ought

Past your foot rest, future promising smart

Past, present and future

Isolated  islands they are not

Judicious Intermingling of time scales

Make music sweet, and a lovely song!
