How can I overcome imposter syndrome?

So I spent over three or four years there, I think four years actually, rebuilding the team, rebuilding the platform, and I guess actually trying to quash imposter syndrome. I worried - the successes I've had at Visa, are they really my successes? Or is it other people around me that have achieved that? So let's go start from scratch again and see if you can repeat some of the things that went well. And I guess, get the confidence for the long term. And again, it was successful.
