You forgot that you have a dream. A dream that brings you to where you are today, and will continue to fly you to the land, which you once imagined before.
You forgot that you are yourself.
When people talk about dreams, you become skeptical about it. You said that is impossible, that isn't the reality and that isn't the way things work.
You forgot to stop and stare.
And, one day, you realise, where is the you that have taken the road not taken?
