Claire, the question you pose and career-path doubt you are going through are normal so don’t fret. Most individuals do not know what they want to do when they grow up
so be gentle with yourself. Quite honestly, it is often a class at school or a volunteer opportunity that triggers interest (and passion) towards a specific field of study or job. In the job realm, work towards something that inspires and invokes passion in you. Waking up everyday to do a job is singularly the most important decision you will make in life since you will devote up to 80% of your week so do something you love. If writing or teaching English is it, then do it. There is no shame in public service or in teaching others the joy of writing and learning the classics that teach us so much about life like love, joy, hope, misery and pain. Follow your own path, not what others have potentially created for you. Be willing to diverge for your internal happiness. Good luck, and knock em’ dead!
