If you end up hating your job just keep looking and find a different company or position. Job satisfaction is so many factors, e.g. how well you get along with your coworkers, how much recognition you get from the higher ups for what you do and so on. The career path you choose now might not affect the outcome that much.
I’ve watched like 10 minutes and I hate it. Peter Singer is a very controversial figure as it is, on top of that the guy in the video comes off as super condescending to me and I can’t stand watching him for longer. Me personally, I don’t think it’s “immoral” to not give money to charity. And terms like immoral or evil are usually defined by the society you live in and not some random philosopher. And I bet there are good reasons his radical ideas in “Famine, Affluence, and Morality” did not get embedded in our society yet.
What is it you are distracting yourself from? The low motivation could also be that you are not really believing in a goal or you are not enjoying a task because you would rather do something else with your time. As others already said if you “suspect” you have ADHD you could also try therapy.
