RE: Creating empathy windows - Ren Gill: A light in the dark

The positives for him with HVAC is that it is very technical, so it requires a solid understanding of certain aspects of physics and chemistry, coupled with strong problem-solving skills, but it’s also very hands-on, so he’s constantly moving and always doing something different, so he stays interested and challenged.

And, he jokes about how someday he'll probably be earning more than his older brothers, both of whom got engineering degrees (thanks in large part to the government regulations that severely limit who can do what with A/C systems and refrigerants).
