"People say to me that I can't be nervous because I've had such a wealth of experience, but I tell them that I have never done this particular part before"

This quote by Brenda Blethyn talks to the idea that experience does not constantly relate to self-confidence. Despite having a wealth of experience, Blethyn is still worried about taking on a brand-new function. This speaks with the idea that no matter how much experience one has, there is constantly something brand-new to find out and brand-new obstacles to deal with. It is natural to feel nervous when handling something brand-new, and Blethyn's quote works as a tip that it is okay to feel nervous and uncertain. It is necessary to keep in mind that even with a wealth of experience, it is still possible to feel nervous about something brand-new. It is necessary to accept the feeling of uneasiness and utilize it as a source of motivation to press oneself to do their best.
