UP into our dreams

I watched the movie UP. It was an animated movie. When I decided to buy the tickets for this simplistic movie, little did I expect myself to tear in the midst of a couple of touching scenes. Reflecting on the movie, I figured that the producer ensured that all of us didn't waste our time watching a 'cartoon'. As adults, we were engaged into the movie because it allows us to relate ourselves to the character played by Carl Fredrickson. Carl grew up as a young inquisitive boy in a small town. He was energetic and even dreamt of being a pilot. He wanted to travel round the world. Along the way, he met with a girl, Ellie, who shared his dreams. Together, they wanted to go to exotic places, such as the natural waterfalls in South America.
They started to save to achieve their dreams. But time flies and they aged without achieving what they dreamt of so vividly years ago. They had to postpone their dreams time & time again, with reasons such as house maintenance, insurance, retrenchment, medical expenses, etc. Ellie eventually passed away. Only then he realised that he had to live his dream & fulfil what both of them set out to achieve in the 1st place.
I asked myself - how determined do I go about fulfilling my dreams? Maybe I should even question how concrete my dream is. Are our dreams as transient as clouds or are they as solid as a rock? Carl & Ellie started their dream by having a scrapbook to visualise what they would do. Should I start one too?
