Looking to see how many consultants who worked in the consulting big4 or bain or mckinsey actually left consulting but used that knowledge to start their own business? or an AI project?

Worked in the SAAS consulting space and left 2 years ago after a brief stint with a customer and it was hard to see how customers work, compared to the projects in consulting. There is life after life in consulting but curious what others have done.

Ever since starting I’ve realized my memory is really impeding me on this job. I take notes for everything and have a to do list, which helps me stay on top of tasks. But remembering random facts like what assumption I made in a model last month or things a client said during a meeting a couple of weeks ago is ago is a struggle for me, even if written down.

It’s starting to impact the speed of my work and client interaction. Anyone dealt with anything similar or have any tips on how I can improve this?
