Ochako Uraraka is a mage and is quite clumsy while doing magic, so occasional accidents happen while she tries. She has no confidence in her talent and ends up messing up. But as she met Midoriya, she gained a little something for the lad. She soon became confident in her craft and began to gain her presumption. She continues to train for her goals as she gets more inspiration from Midoriya, she is pretty used to how clumsy HE IS as well..
