Try to force yourself to treat it like practice. Because that’s what it is (in the grand scheme of things). I liked to think of those early jobs and summer gigs as just stacking up experiences and reps to get used to it and comfortable/confident before I got to the important stuff. I worked a couple different service in industry jobs as a teenager and in the summers and it was really awesome practice and the best way to desensitize myself. Because as a waitress I would interact with countless tables each day. Sometimes my speech was better sometimes worse. But I built up some really good mental toughness and techniques to manage my headspace and ability to wipe it from my mind and keep moving. Lean in and get reps when the stakes are low. Ten years from now, future ‘you’ will thank you for it - trust me.
