In the newspaper business there is no such thing as writer’s block. If you’ve been out covering a story and you find yourself staring at a blank screen not sure what to write, then you haven’t done enough reporting.
That means you haven’t asked enough questions, talked to enough people or researched the topic enough.
The same can be said for finding your purpose in life. If you don’t know what your purpose is yet, it’s not that you don’t have one, it’s that you haven’t done enough digging. If you’re stumped, then you have to get to know yourself.
