Without even a little bit of sarcasm, I am genuinely happy for you. Hold on to this job for as long as you can, because people like that are incredibly rare.

In my 30+ year career in IT I've only managed to work for a place like that once. It was 20 years ago, and I was the sixth employee to be hired, and at our peak we were at about 30 people. The owner was a super nice guy who cared about every single one of his employees. I learned a lot from him and consider him to be a friend and a mentor. We weathered the 2008 financial downturn better than most, but eventually business started to dry up and the company was sold to a large competitor. The boss was relegated to a consultancy role, and eventually got pushed out altogether. I lasted another 3 years at that place, but it was never the same after the buyout. Everyone became just another cog in the machine. Every place I worked at before that or since was your typical corporate position where my manager's supervisor's boss doesn't even know I exist, much less care about me.

I consider the first 6 years in that company a highlight of my career, and keep in touch with that boss and others who worked there. So yes, treasure your time at a good workplace, and don't take for granted the personal connections you make there.
