While I was making the pizza I dropped the dough on the ground.
What caused you to drop the dough?
There was a strong wind that blew the dough from my hands.
That's a bummer that you dropped the dough, but accidents and unavoidable things happen and you should not stress over it. Throw away the dropped dough, as it's now ruined, and start anew.
I know, it just made me feel like a failure.
Don't be so hard on yourself. You did the right thing by throwing it away.
