Bubblegums!

Have you ever wondered why good things come to an end?
Have you ever wondered why after you smile, most probably you'll cry the moment after?
Have you ever wondered why people love and hate each other the next?
Have you ever wondered why people come and go?
Have you ever wondered why there's a beginning and an end?

If you say 'yes' for most of the questions, congratulations, you've earned yourself a life.
If you say 'no' for most of the questions, go out a little.
Live a life, experience miseries, let yourself cry, hurt, angry.

Imagine life as a scale. If the right side is heavier than the left, it won't reach the balance state. If it doesn't get to the balance state, everything will go out in chaos. Even though both right and left side are good things, they still have to be measured in an exactly same capacity.
For example : imagine HAPPINESS is heavier than the SADNESS, life will probably be good for the first few minutes, but then when happiness started to take over, later on, life will become... flat. People don't realize what's HAPPINESS anymore, because they've never experienced SADNESS.

I'm asking you this,
Are you sure if there's no negative deeds, there will be world peace?

And then, 'THE ENDING' takes place. There'll always be ending in everything. Either good things or bad things. People sometimes forget to see the other side of them. They'll always whine about why good things come to an end, but they seldom remember that they've felt grateful that bad things come to an end before.
Life is a sequence of BEGINNING-ENDING-BEGINNING-ENDING-.....
So, when you stated something as the ending, remember, it's also the beginning of something new.

All you need is to change your perspective, ergo, look for a lot of sides.
