"I trust myself to have the power
To climb to the top of the highest tower
I see myself up there, looking around
Discovering new freedom I've just found"
I think It's the heart of your poem.
"trust myself " = "the highest tower" and "the power" = "freedom".
That words just like a very harmonious couple of words.
I don't believe if you wrote by your self, it's should be from great psychologist!
