We often says about our life length,
"A life is long" and "A life is short," both.
But if sometime in our lives
we feel that our lives may be shorter than we have recognized before
and think such,
I think that we must change to use our life time
for something we recognize as really valuable for us.
We must turn to be honest to ourselves
and to select next actions more carefully.
When we get those scales for judging usages of our life time in our mind,
we could know our true hearts as floating up from the bottom of our hearts.
We may feel those are time losses
when we do actions which do not suit our feelings,
for example, by lying to our hearts.
Every action represents our real hearts inside us, I think.
