It is sunny and joyful outside

It is sunny and joyful outside.
Birds are singing , grass starts to grow.
I decided to change my attitude
and stop being not in the mood.

I of course will never be merry.
Or will be , at least I will try.
Is it possible to start smiling?
Or too be pessimistic - my doom?

I met him, he is my energy.
He makes me move in this world.
I have changed so much already.
will I be a wag one day?
