There is a common assumption that writers don't live lives of their own. They spend their life documenting or studying others, and turning those documents or studies into stories, so they never get to do any of the fun stuff - they only watch.
It seems like this belief is held by writers and nonwriters alike. Certainly, there are outliers, but it feels like so many writers are these timid or dull creatures who sacrifice their own life to enrich others.
But the sheer existence of outliers proves that such is not a rule. You can live an interesting life and also write about it. You could also write about anything else other than your life. It's your choice.
