Hi Pablo, what you feel is natural, asking questions and wondering whether you are doing the right thing. You have taken the first step. Three years ago, I completed my second Masters. It was hard work. I did it at the same time as working. But you know what? I enjoyed every minute. I acquired new knowledge. I felt alive, and I loved the buzz of acquiring new knowledge. Wishing you all the best on your new journey. We all must work within the system while maintaining our core values. Your family and friends are your bedrock. The survival of humanity requires change. So, hopefully by the time you finish your course the world will be a different place.
