Many professionals are faced with a tough tradeoff in career planning: Should they pursue what they are most passionate about, or should they pursue what they can have the biggest positive impact on?
Some people put their own interests first. They believe that they will be more motivated and satisfied in the long run, and this will make them perform better and contribute more. Others target areas where their skills and efforts can resolve major issues and benefit the largest number of people.
There’s no single answer, and how people prioritize such factors will vary based on their goals, values, and circumstances.
How do you reconcile your own passion with the desire to make a difference?
AFAIK research suggests that people are terrible at predicting what they would enjoy. (Check 80k for this). But personal fit is a crucial thing, once you actually tried (seriously and with being as open as you can) and it does not feel right, you should move on and try something else. After a few diverse “samples” you should get a rough idea of your options and decide what to stick with.
