What career would suit someone who’s skilled at their craft but wants to avoid office politics? I'm not the type of person who's good at or tolerates mind games or office politics. I'm actually a really hardworking person who excels at what I do. So, if this has happened to you, you understand the situation - it's not pleasant. In this case, I'd like to leave my current job... or rather, career. I'd like to find a career where there's no need for office politics, mind games, or being discredited by others, but rather, where the quality of my work speaks volumes and attracts clients. Can you recommend a system for understanding what factors to base my new career on? (i was thinking of physical theraphy)
