its up to....me?

I get discouraged now and then
When there are clouds and gray
Until I think about all the things
That happened yesterday

I do not mean the day before
Of those of months ago
But all the yesterday in which
I had a chance to grow

I think of opportunities
That I’m allowed to die
And those I took advantage of
Before they passed me by

And I remembered that the past
Presented quite a plight
But somehow I endured it and
The future seems all right

And I remind myself that I
Am capable and free
And my success and happiness
Are really up to me….
