Everything you say is agreeable, but I would add that being success oriented in life cannot be the only driver and that by doing that we miss other important steps in our personal development. There has to be a time for doing something that is NOT useful, for staring at the beautiful things in the world, for thinking, for playing an instrument - not just because you're entertaining someone or showing your skills but just because you enjoy it - for learning ancient Greek, time for loosing time, for listening. Don't misunderstand me, I agree with what you wrote, especially, if someone has a dream - and everyone has - we need to stop finding excuses and just pursue it. But sometimes the beauty of being human lies in our capability to just question the skies, and not in giving answers.
