Dreams are unrealized potential. They are things we have manifested into our minds as desires of the future. They are a life we could have if only.
What of reality? What of the here and now. If our dreams never come true, can we be happy with our lives now?
No one is promised tomorrow. Life could end at any minute. Is it better to chase dreams or make your current life a dream itself? Is life just a precursor to your real life? Could you live a happy life without if only?
