Answer:
When I was a little I wanted to be Luke Skywalker and fly around the galaxy destroying evil space stations. But things happened and I'm still waiting for the opportunity to kill Darth Vader, although I'm planning to visit Disneyland and maybe I'll be lucky.
Putting aside my childhood dreams, I grew up and discovered that the world was a little bit more complex and it didn't include space travel (and Parsecs are not a real time measure).
Life provides us with a lot of experiences and knowledge, along with may changes in our lives and our surroundings. Every single day I try to find a reason why I should be happy and enjoy the day, and what makes you happy is not blowing up the Death Star or visiting a waterfall in the Amazon. Small daily experiences are what makes us happy and they allow us to enjoy life. The pursuit of happiness is a daily trail, not a destination point.
