I feel crushingly embarrassed when I do bad work, so being rejected after doing bad work is actually harder than being rejected after doing good work.
I work constantly to be better at being rejected.
Even in success, you're going to be constantly rejected.
Being an actor is definitely not the hardest job in the world - it's definitely a first-world problem to have, but I'm not very good with rejection. I constantly question whether or not I'm suited for this business, because it is your job to get rejected.
Offers come up, but I'm still fighting for jobs and auditioning and being rejected.
