Thank you very much for your insight!
There will be sacrifices you will have to make to succeed, but I hope that in the end you will achieve your target. Every time I was in the middle of a career change, I feel all this effort and sacrifice aren't worth it; I can just enjoy what I have. I don't succumb to that feeling and work harder.
You are the only one who can decide if the prize at the end worth the sacrifices along the way.
