As I was looking through Mh's thank you dinner08 photos. I think I finally realised the true meaning of the words opportunity cost.

I first learnt these two words back in JC1 during my econs class. Back then it was all about how making 3 more red pencil boxes may mean you could make 2 less blue pencil boxes.

Now it means giving up spending quality time with dear friends for making new ones.
It means giving up comfort zones for new experiences.
It means giving up time with family for discovering new things.
It means giving up celebrating my best friend's 21st for experiencing a different life and culture.
It means giving up things and people I love to discover more things and people to love.

I felt overwhelmed and all I wanted to do was cry. If I could only go back to Singapore right now.

But really who am I to complain? Just today I touched the Berlin Wall. A few days back I was at Oktoberfest. Before that, Venice, Rome, Florence and many more.

I'm living a dream. And like all things, dreams have costs.

I know my costs now.
