time

time:
seconds
minutes
hours 
days
weeks
months
years

if you ask a professional timekeeper they will tell you 
a second is always a second
a minute is always 60 seconds
an hour is always 60 minutes
a day is always 24 hours
a week is always 7 days
a month is 28, 30 or 31 days
a year is 365 days unless it is a leap year, then add a day

ask a real person and they will probably tell you 
that all time is not created equal
"wait a second" is rarely a second
"just a minute" is never 60 seconds
an hour can be endless
a day can be but a moment long
a week can last a lifetime
a year can pass quicker than you can blink an eye

time:
it is one thing
we cannot manufacture
we cannot buy more of
we are not guaranteed 
we often take for granted
we cannot "save"
is invaluable

time spent loving 
requires thought
indicates commitment
is not cheap
is never wasted 
is an investment
is not "one size fits all"
is one thing that will outlast our life
