Instead, I've worked in Product for 26 months and learnt some really good skills: how to write real requirements, how to manage expectations (up and down), how to negotiate, how to measure and to focus on moving the needle, how to build a GTM plan and execute against it, how to deal with fireman issues, how to develop with a SOA, the list goes on.
And picked up a bunch of payments industry expertise along the way.
I'm still determined to start my own business, but definitely a hell-of-a-lot more confident in my chances of success.
