You're absolutely right good friend, we a want a purpose driven life.. It's very inspiring to see how you've found purpose, especially in a career transition. Balancing passion and responsibility can be tough, but it sounds like you've been able get a fulfilling balance.
It's the goal I think of everyone out there, to live for something bigger than ourselves and to find meaning.
You're absolutely right on this good friend... We certainly have to live for something bigger than ourselves... That's what makes life worth living
