To give the most generic advice to all who read this: make a living by making the lives of others liveable. Many are determined to study X and have a career of Y. This sometimes works out. Many will repeatedly try to have career Y their whole life due to a fixation even if it isn’t right for them at any or all those times. Some of the most lucrative success stories have been people who saw someone else in need and helped them, someone else or a subset of the population who had a problem that nobody came around to fix yet. A problem you had no prior affiliation with. Opportunity Z may be wildly unrelated to your training and/or career path, but, it may help more people moreso than your career Y. And then, your X, Y and Z skills can compound when you find your next opportunity.
