Twenty years in, and I'm still learning. But if I could go back and give younger me some advice, it would be this: the technology matters far less than the relationships. Every successful engagement we've had came down to trust, communication, and actually listening to what people needed.
I spent years thinking technical excellence would win the day. It doesn't. Being genuinely helpful does. Being available when things go wrong does. Remembering that behind every support ticket is a person trying to do their job. That's the stuff that actually matters.
