Even though it was tough, Ryder didn't let this get in the way of chasing his dreams of being a successful musician.

"But by the second weekend, there was just no stopping Ryder. He would be up again, jamming and doing more shows." He maintained an incredibly positive attitude, given everything he had been through.
