That whole album was and is definitely worth the listen. It may begin and end with Blue, but there is quite a range of emotions and messages. When I was young, Blue was my favorite, but as I grew up, different songs started to resonate with me.

Track 02 = anti-consumerism
Track 04 = anti-selfish realism
Track 07 = love triangle heartbreak
Track 10 = optimism, encouragement, and hope

we should think about,
what we got right now,
cause the good things are made up of time.
smile to your problems,
leave the past behind.
never forget this.
find the truth in your soul,
keeping you alive.
going on from minute to minute.
don't shade the future,
with all that's behind.
live for today.
[...]
don't shade your future,
with what you don't have.
keep your mind on what's here today.
now and forever,
build the future now.
keep this mind.
though you will take your time,
to get what you need,
but you'll do it step after step.
yet to come is all that's gone,
learn to live this moment.
live for today.
[...]
the past is all that's gone (the past is all that's gone)
the future is yet to come. (and the future's yet to come)
this moment is all our own. (you know it is)
we should live this way,
just building up our day,
now is forever.
the past is all that's gone, (the past is all that's gone)
the future is yet to come. (the future is yet to come)
this moment is all our own.
we should live this way,
just building up our day,
now is forever.
