We just never know

what goes ahead
the next trip
the next track
sometimes we think we know
we've planned
we've dreamt

but in fact, we're all dynamically may change.

the nature change.
science theory broken. weathers are unpredictable now.
incurable disease come and go.
all things change.

people change.
the toughest person i know may fall, too.
the wisest figure i know may weak, too.
the one i think i know best, also may hurt me, too.
people may lose their head.
their heart.
even themselves.
nobody's perfect.

life track
life line
life stories
the actors
the crews
seasons

they're all come and go.
they may change.
we just
never know.

The good you do today, will often be forgotten. Do good anyway.
