AuDHD, always took the hard road on life and ended up tangential to sales. A lot to learn from sales people, every day all day is rejection and their #1 talent is being upbeat and optimistic in the face of rejection. Knowing, really internalizing, that it doesn’t actually matter because there are a million other opportunities.

Personally I find the best mitigation is having multiple attempts at whatever I’m highly likely to get rejected by in parallel. Multiple dates, multiple job interviews, multiple work projects, multiple sales pitches, etc. When there’s hope it feels different.

Over a hundred job interviews made for good exposure therapy, if I’m rejected at something important that I’m emotionally bought into I’ll still be devastated, but the key is to have something to hope for that’s independent of the rejection.

At least that’s what helps me. YMMV.
