Do these questions have answers?

I read this poem somewhere:

If I knew it would be the last time that I'd see you fall asleep,
I would tuck you in more tightly, and pray the Lord your soul to keep.
If I knew it would be the last time that I'd see you walk out the door,
I would give you a hug and kiss, and call you back for just one more.

If I knew it would be the last time I'd hear your voice lifted up in praise,
I would tape each word and action, and play them back throughout my days
If I knew it would be the last time, I would spare an extra minute or two,
To stop and say "I love you," instead of assuming you know I do.

So just in case tomorrow never comes, and today is all I get,
I'd like to say how much I love you, and I hope we never will forget.
Tomorrow is not promised to anyone, young or old alike,
And today may be the last chance you get to hold your loved one tight.

So if you're waiting for tomorrow, why not do it today?
For if tomorrow never comes, you'll surely regret the day
That you didn't take that extra time for a smile, a hug, or a kiss,
And you were too busy to grant someone, what turned out
to be their one last wish.

So hold your loved ones close today, and whisper in their ear,
That you love them very much, and you'll always hold them dear.
Take time to say "I'm sorry," "Please forgive me," "Thank you" or "It's okay",
And if tomorrow never comes, you'll have no regrets about today.

They say you should always leave loved ones with loving words, 'coz you never know.. it may be the last time you see them. But is that how life works? Every day of your life when you talk to your family, friends, etc., is this what you think about? If you have an argument with someone and you decide to give the other person time to cool down before you talk again, is that not contradictory to what I first said? Or do these feelings come in only when you do lose someone and then fade away? Do we actually have the time these days to think about all this? Should we even think about all this? Should we not live life to fullest?

They say life is short.. is it really? If you've lived 20 years, isn't that a long long time? They say you shouldn't let little things bother you.. they say you must forgive and forget.. If you're upset because of someone or something for one day, is that bad? If 20 years is a long time, how small is one day? How can you live everyday just being happy? They say you should everyday as if it was your last.. Can you do that? If people say things to you and don't behave well, should you let that go? What happens to your feelings? You give someone time to get alright, but even during that time, doesn't it matter to you how that person behaves? Isn't life made up of little things anyway? And if they say life is short, then every little thing should count, right?

What is life really all about?

Don't worry, be happy!

Sometimes I wonder why things that happen in our lives, happen at all. 'Coz some of these things change your life entirely - may be forever. You wish that some things never happened, or certain other things happened - but what we always forget is that if everything happened our way, wouldn't life become too predictable and boring? You would just say "I want it that way" and it would happen - no, that's not what life is all about. You need to experience unexpected things and derive excitement and happiness from those things, cos if there are no chanllenges, there's no excitement. Challenges come in 3 categories - easy, difficult, impossible. Those who take on the easy alone have a boring and staright forward life. Those who take on the difficult have a tough but satisfying life. Those who take on the impossible are remembered forever! (I read this quote somewhere) Always remember - all that happens, happens for good. If God does not give you everything you want, it is because there is a reason behind it - and it is for your good. Time will teach you everything, even if you don't understand it at the moment. 'Coz time is the greatest healer..
