The advice “follow your passion” is both wrong and potentially dangerous.
Focus on what value you can bring the world (craftsman mindset) instead of what value the world can bring you (passion mindset).
Working right is more important than finding the right work.
Don’t obsess over discovering your true calling. Instead, master rare and valuable skills. Once you build up the career capital that these skills generate, invest it wisely. Use it to acquire control over what you do and how you do it, and to identify and act on a life changing mission.
A mission is a unifying goal for your career. Good missions are most often found at the cutting edge of your field.
Ask: “Are people willing to pay for this?” If yes, continue. If no, move on. (Doesn’t apply for hobbies).
