Interesting topic, my wife is 100% supportive to wards my training (so far) I guess the fact that my biz is paying for half of it helps! However, I would never do anything to jeopardizes my families financial stability to pursue personal goals. I think family support is crucial when taking on large challenges both mentally and financially.
I'm 29 and wish I did it younger while still living at home and just worked to pay for schooling!
