You shoot me in a dream, you better wake up and apologize

My mind is a tree of growing dreams
It seems like it produces more each day
But with every day that passes
There is also a forgotten one
When you add all the forgotten ones
you get a tree that is dry 
A tree with many rings
but with one leaf
One green leaf that appears
every day but also dries up 
when the next day comes
When a tree only has one leaf
no one really looks at it
It is a tree with no ambition
A tree with only one dream
No one wants a tree with one dream
especially if it is never fulfilled
