That' Once Found

After many years of declaring my identity.
With an opposition to be 'me' on occasion.
I set out on the pursuit of one thing.
And one thing only!

That...
'Was' my purpose.
That...
'Is' my purpose.
And 'that'...
Once found,
Can not be reversed.

I have never had the option,
Of a practiced rehearsal.
Or a flaw I had to welcome,
To live with and overcome.
