Sins and Regrets

Is it alright to regret
more the things I have not done
than all the things I have?

My mistakes I've learned to accept
but not my yet unreached triumphs.
So much time I have wasted
dreaming of what I could be doing.

But must I mourn my fall to Sloth,
in hopes I will find my muse
when productivity becomes my virtue?

Or perhaps I must simply take hold
of all these sins and regrets,
and change them, morph them
into something new.
