Ask HN: Has anyone been able to transform their personality?

For context I'm naturally introverted, never been consistently great in group social situations and struggle sometimes in 1 on 1 situations with naturally outgoing people. I'd like to feel more at ease with myself, feel more comfortable contributing in an authentic, confident, light-hearted way. But instead I'm often in my head over-analyzing instead of being present.

Has anyone here been able to transform their personality from one that is filtered/socially anxious/stoic to one that's fun/ confident/at-ease? If so what steps did you take to make this transformation?

Appreciate the help.
