Important things you are writing about here. The attitude we choose towards life has big consequences. Cynicism is often a way of limiting yourself and your scope of options. Sometimes it is an "out" from taking responsibility for your life. however as you mentioned we know live in a world with more possibilities than ever before. I think Peter Diamandis said it very well ( paraphrasing ) : "this is the time when we should stop complaining about problems and begin solving them".
