Spirit of a servant.

I have the spirit of a servant,
And sometimes it does me harm.
I am bubbling inside,
But I put on the face of calm.
I do not tread my own path,
I act as if to please.
I am seldom brave enough to speak my truth.
It does not come with ease.
I would like a simple life.
It is not mine to live.
I lost my power over time,
And have only myself to give.
