I think expanding to other platforms in a bid to increase your reach is all about timing.
Focusing on one or two areas first and getting really good at them is a great strategy to begin with - as you mentioned.
Then, once you've put in the work, grown a following, gained traction and have a consistent stream of readers/viewers/listeners to your content this, in theory, should give you more time to play with and explore other options without the fear of becoming irrelevant elsewhere.
Thanks for sharing this piece, I know it's going to be a great motivational boost to many.
