I actually fell into it by chance and luck - because I love it! My first ever customer success job was over 20 years ago now. It wasn't called Customer Success, but that's what it was.

Not learning more about the business, which is why I tell folks to dig in deep. When I say business, I am referring to both the ones you work in and the ones you support. You cannot be a trusted advisor if you don't understand your customers day to day, and you also cannot control your destiny if you don't understand the whys behind what you do.

Learn about the business you are working in and supporting. You should know what NRR is, what impacts it from the business standpoint, and what levers you have to impact it. You should know what renewals are coming up for your book of business, not just a quarter out, but a few quarters out - because the further you think and strategize, the greater the chance you can positively impact that renewal event. Oh, and don't be afraid to own a number. It may be scary at first, but ultimately will help your career.
