> I'm not sure how to signal to companies "my deal is I want to do things; I will more or less literally jump off my seat to assist anyone and no job is beneath me and I will stay up and work 16 hours straight if I screw something up; but I'm not really good at hearing no".

"I have a proven track record of executing relentlessly, rapidly delivering value, and moving between internal roles effortlessly. What challenges are you facing I could contribute to in a meaningful way?"

Be more comfortable hearing "No". Trust takes time to build.
