It's complicated, I imagine that your parents had to make a great effort to survive the time and I understand it very well because my circumstances were/are very similar to what you describe, and it's hard to do the math when the priority is to eat.

I'm 50 years old and I'm still learning a lot of things to adapt to this new world, technology will continue to evolve and we will continue to run after it, but if I can tell you something is that passions are trains that never let go.
